Right now, in Music libraries, only artists can be added to a collection, and the collection filter is only available for artists.
To me, this feature would appear more useful on the individual album level. Especially various artists albums often come in series (e.g. Pure Music 1, Pure Music 2, ...)
I've looked at the web API and the database structure, and it looks like it should be trivial to implement this (at least for the web app, haven't checked the other clients).
I have some albums with various artist like the Top of Pop Collection.
Putting "Top of Pop" in the Orchestra field of the mp3 allow Plex to group them as if they were of the artist "Top of Pop" while maintaining the name of the band/singer for each individual song.
Keeps my library clean instead of having thousand of artist with one song only...
I agree, setting the Orchestra tag (or the Album Artist tag, for that matter) to something other than Various Artists to fake an Artist, could be a workaround. But it feels messy. I use MusicBrainz picard to tag my albums, and they are correctly tagged as Various Artists. The collections feature is there specifically to group related things. It's strange that this has not been implemented for albums.
I have been able to verify that the PMS itself does in fact support collections for albums. Using the API, you can add a collection tag to an album, and you can retrieve a list of albums filtered by collection tag. This works both for new and existing tags.
I just tried adding a music library and instantly noticed this feature missing. How come? This seems much more useful for albums than for artists. Please implement this for albums as well.
It would indeed be very nice to have collections for music album series. It is annoying having volume 1, volume 2 and so on. Since you can already add the tag all that is needed is the collapsing we have in the movies view.
That’s a different request than the OP. What the OP asked for was implemented 3 years ago. You should add your request as a new topic. It will just be ignored while it’s buried under an old thread.
