**MusicMind for Plex v2 is out — real audio analysis, not just AI guesses**

Hi everyone — quick update since the original post. v2 shipped, and the  
headline feature is a direct answer to something that came up in this  
thread: wanting to know _exactly_ what the software is doing to your  
library.

**Synapse — local audio analysis.** MusicMind now analyzes the actual  
audio of every track on your own hardware: real BPM, musical key, and  
danceability, measured from the waveform using Essentia (the open-source  
audio analysis library from the Music Technology Group at Universitat  
Pompeu Fabra). No cloud calls, no guessing from titles — deterministic  
signal processing on your files. It runs as a background job you kick  
off from the admin page, it’s resumable, and it gives you a time  
estimate based on your own hardware before you commit.

What that unlocks:

- **BPM and danceability filters** in playlist generation — “upbeat  
running mix around 170 BPM” now means literally that

- **DJ-ify** — reorders a playlist for flow, using measured BPM and key  
for smoother transitions

- **Last.fm date search** — `lastfm:` prompts plus an “On This Day”  
picker to rebuild what you were listening to on any date in your  
scrobble history

- **The Collection** — a stats dashboard for your library and listening  
history (by era, country, genre, and more)

Also new: a proper CHANGELOG and SECURITY policy in the repo, and the  
project rename to MusicMind for Plex is fully complete (thanks again to  
tom80H for the trademark heads-up).

**What’s next — and a confession.** v1’s instrumental tagging asked an  
AI to judge from artist + title text alone. I recently audited that  
against actual audio analysis, and the results were humbling: roughly  
half the “instrumental” tags were wrong. (A track called “Wordless”  
turns out to have vocals. The AI never stood a chance.) So I’m  
currently re-verifying my entire 17,000-track library with a local  
voice/instrumental model that listens to the actual audio — same  
philosophy as Synapse: measure, don’t guess. That lands in the next  
release, and text-based instrumental guessing is being retired for  
good.

Feedback very welcome — especially from anyone who tries Synapse on a  
big library. Curious how the analysis times compare across hardware.

I tried different plex baseURLS. Just odd it would add tracks to the db, but not run the synapse or any other web-app related options

Hi Mark, thanks for the info!  
The `/run/<script>` route lost its function binding in a v2 refactor, which broke every generic admin run button (the “connection failures” are the same bug — the admin page streams those jobs, and the stream dies on the 500). Fix is pushed to main. `git pull` in your musicmindforplex directory and restart the app (`pm2 restart plex-music-brain` or however you’re running it), and the admin buttons should come to life. The command-line scripts you already ran are unaffected — your ingest and enrichment data is all good. Let me know how Synapse goes on your library — genuinely curious about analysis times on other hardware.

I appreciate you trying it and reporting the bug!

Thanks,

Louis

Hi Mavproductions,  
Two more real finds — thank you. Both fixed on main, so `git pull` first.

**Enrich Artists crash:** the `artist_meta` table was only created by a script that runs _later_ in the setup order, and its schema was missing a column newer code expects — worked on my install only because my database predates the code. Fixed: both enrichment scripts now create/upgrade the table themselves, in any order. After pulling, just rerun `python3.12 mb_enrich_artists.py`.

**Synapse samples all failing:** the estimate was unhelpfully hiding _why_ each sample failed — that’s fixed too, so after pulling, rerun `python3.12 synapse_analyze.py --estimate` and it’ll print the actual error. My strong suspicion for the root cause: a numpy version clash — essentia’s prebuilt wheels don’t work with numpy 2.x, and a fresh `pip install essentia` in a new venv usually pulls numpy 2. Quick check: `pip show numpy | grep Version` — if it says 2.x, run `pip install "numpy<2"` and try the estimate again. Post whatever error the estimate prints either way and we’ll get you analyzing.

(Also, small thing: `--estimate` and the full run are two separate commands run one after the other — looks like they got pasted as one line. The estimate ignores the extra arguments so no harm done.)

Again, thanks for your feedback. V3 will not be shipped with these install issues!

So I think the problem actually is my Plex server runs on Windows, and I’m running musicmind in WSL.

* * *

> Plex is returning file paths in Windows format (`J:\Music\...`) — meaning your Plex server (`blah-plexserver`) runs on Windows and sees that music library on its `J:` drive. But `synapse_analyze.py` is running inside WSL (Linux), and essentia’s audio loader (built on ffmpeg) tries to parse `J:` as a protocol prefix — like it would parse `http:` or `file:` — and fails with “Protocol not found” because `J:` isn’t a real protocol. It’s not a filesystem-not-found issue, it’s a path-format mismatch between the two OSes.
> 
> For this to work, WSL needs to translate Plex’s Windows paths into paths it can actually read — either:

Nailed it — that’s exactly the problem, and you diagnosed it better than my error message did. Plex reports paths as _its_ host sees them, and until now MusicMind assumed it lived on the same filesystem view. That assumption is now gone: `git pull`, then add this to your `config.py`:

python

```auto
PATH_MAP = {
    "J:\\Music": "/mnt/j/Music",
}

```

(Adjust to your actual paths — longest matching prefix wins, and backslashes get converted automatically.) One WSL wrinkle to check first: if `J:` is a _network_ drive, WSL doesn’t auto-mount it like it does fixed drives — `ls /mnt/j` will tell you. If it’s missing: `sudo mkdir -p /mnt/j && sudo mount -t drvfs J: /mnt/j`.

Then rerun `python3.12 synapse_analyze.py --estimate` and it should start timing real samples. Also run `sudo python3.12 enrich_compilations.py` again after configuring — it reads files directly too and was silently failing on the same paths. Your setup (Windows Plex + WSL) is genuinely useful territory for the project — thanks for pushing through the rough edges.

Still getting enrichment error. Path\_Map + sudo mount command seems to clear up a few errors.

As it stands right now is this thing gonna break if I try to make any playlists or is synapse required?

Sorry about that!

Pull again — you found the last (I believe) of a whole family of these: three columns (`real_artist`, `is_instrumental`, `genres_written`) that were added to my database over months of development but never made it into the table-creation code, so fresh databases were missing all of them. The ingest script now creates the full schema and auto-upgrades existing databases. After pulling, run `python3.12 plex_music_brain_ingest.py` once — it adds the missing columns to your existing DB in the first second, then refreshes your library data — then `sudo python3.12 enrich_compilations.py` should finally behave.

Straight answer on your question: **Synapse is not required for playlists.** Prompt-based generation needs only ingest + the AI tagger, which you’ve run. Synapse powers the _extras_ — BPM/danceability filters and DJ-ify — which will just be unavailable until it runs. But honest disclosure: before this fix, playlist generation would have crashed on your database anyway (the missing `real_artist` column sits in the core search query). After the pull + ingest rerun, generate away — and I’d genuinely like to hear what the playlists are like on your library.

Thanks for your help -  
Louis

I get that. It is an ambitious project. Unfortunately, from where the concept started to where I am now was a messy road. Sharing it with the world wasn’t even my goal, but I was enjoying so much! As such, I have built upon the app and in the process added tables for new functions that were not created in the original setup. Your help has been very valuable in discovering these bugs. I know it will be a worthwhile app once the kinks are ironed out.  
For what it’s worth, the fix for this latest one is already pushed — and having now audited the whole schema, I believe you’re at the end of the setup gauntlet, not the middle. One pull + one ingest rerun and the pipeline should be open.  
The ingest script now creates every core table itself, so it works standalone in any order. Rerun `python3.12 plex_music_brain_ingest.py` and it should complete cleanly this time — including that reconciliation step, which by the way was doing its job: it noticed tracks in your database that are no longer in Plex and was trying to tidy them up when it tripped.

One suggestion given how these early bugs cascaded into each other: after this ingest succeeds, rerun `python3.12 plex_tag_tracks.py` too — your first run of it may have died early (on a bug fixed two days ago) before tagging much, and tags are what playlist generation runs on. Then you should be fully in business.  
I didn’t mean to ‘outsource the pain’. I have created a test silo, so I can test it more fully going forward.

Sincerely,  
Louis

I’m getting somewhere now, have my collection page populating quite a bit, besides (currently) “Library by Era/Country” and “Artists by Gender”.

Running Synapse now, ETA 23.4hrs.

Tried playlist generation and “what you were listening to on said date” and those worked. 🙂 After synapse, I’m guessing it will be a running of instrumental analysis, then go from there.

Glad to hear it!

On instrumental analysis: honest heads-up before you spend the time. The current `tag_instrumentals.py` classifies from artist/title _text_, and I recently audited it against actual audio analysis on my own library — roughly half its calls were wrong. I’m mid-migration to a model that listens to the actual audio (same philosophy as Synapse), which lands in the next release. You can run the text version today if you want the filter populated now, but I’d wait for the real one.

Run `python3.12 mb_enrich_artists.py` then `python3.12 enrich_artists.py` — both are fine to run while Synapse works, and the tiles should light up after a page refresh.

Also, your Synapse ETA is a genuinely useful data point — that works out to roughly 4× faster per track than my NAS’s Celeron. Exactly the cross-hardware info I was hoping to gather. Curious what the final wall-clock ends up being.

Also any chance since synapse is a long process, that you could include some sort of usage of the already synapse’d music into the AI playlist generation, along with showing a list or data visualizer of songs/artists that have or have not been synapsed via percentage of completion or something of the like?

I love this, and I hope Plex can see this loud and clear that this is where their OpenAI should moving forward with.

Also:

Could you possibly add more filtering of songs? I kind of like how it has unplayed already, but I’d also like the option of “comfort picks” with songs too. IE. Songs I have 𝑥 amount of plays already of.

Having some sort of filter for “popularity picks” would be nice too, as I’m sure in my library in-particular, that I have songs that have 0 plays, but have the popularity icon(🔥) that plex uses built-in.

To answer your older question first - if you had to restart the scan, yes, it calculates a new estimate.  
Already synapse’d music IS available for playlist generation. But adding a gauge would be helpful - I will work on it for v3!  
“Comfort picks” will aslo be added (the logic is there, it’s just not wired), as well as “popularity picks” - I never considered using that data. But now I am intrigued!  
Thanks so much for all your feedback! I really do appreciate it. It has been invaluable. Now i have testing silos and a dev branch of the repo, so I don’t present buggy work.  
Dig into your stacks!

**MusicMind for Plex v3 is getting close! 🎉**

I’ve been hard at work on v3, and it’s shaping up to be the biggest release yet.

Some of the highlights include:

- 🧠 **Synapse** — real audio analysis (tempo, key, danceability, instrumental detection)
- 🎯 Smarter playlist generation with improved search logic
- 🎵 “Based On” recommendations for both tracks and artists
- 📻 Much deeper Last.fm integration
- 🎧 Acoustic fingerprinting to identify the real artists behind many “Various Artists” tracks
- 📊 Playlist Audit, Query Logs, and CSV export
- 🚀 Better performance, reliability, and a much more polished user experience

One of the biggest changes isn’t a feature—it’s the philosophy.

MusicMind now uses the best tool for each job:

- Measure audio when it can be measured.
- Use trusted sources like MusicBrainz, AcoustID, and Last.fm when the data already exists.
- Use AI only where interpretation actually adds value.

The result is a system that’s smarter, more transparent, and much less dependent on AI than previous versions.

I’m putting the finishing touches on v3 now. Thanks again to everyone who’s been testing, suggesting ideas, and helping shape the project. I can’t wait to get this release into your hands.
