It would be great to have a good, working music agent as the lastfm agent doesnt always match/find the correct album/artist and I havent found Discogs to be much use either yet. I have seen other posts on forums regarding this but think its a pretty big deal especially if your working with bigger libraries.
I basically just mentioned this in General Disussion because of how bad the data being pulled is. First, I would like to know if Plex Premium Music is still pulling data from last.fm and 2. If it is, is there another agent we can manually add that responds to a site similar to TheTVDB that allows it’s users to update information themselves. I have A LOT of rare music and I know there are very few sites out there, especially database ones that will have information, covers, etc. on these Artists / Bands.
Premium music libraries use Gracenote by default.

I have found, though, that Gracenote is also fraught with errors, especially for classical music. I eventually put in the effort to get the embedded metadata in my music files squared away, and have minimized Plex’s use of Gracenote or Last.fm.
2021 clean-up: implemented (Plex Music w/ data e.g. from Musicbrainz)
