Plex Music Agent - how often is Plex's database updated from sources?

As I understand it from this post the Plex Music agent gets data direct from Plex’s own database.

And the Plex database is populated from MusicBrainz, Last.fm etc

I have done some additions to MusicBrainz, how long does it take this Plex database to be updated to reflect my additions?

These should arrive in about 72 hours.

I should add: “after the changes have been cleared by the MB community”. If your changes still appear with a yellow background over on MB, they are still open for debate. Data edits in this state will very likely not be forwarded via the MB API – and thus get into Plex.

Yes, I understand

Hi there, I’ve been searching and searching but couldn’t find answers. The majority of my artists (2500) match fine using the default ‘Plex Music’ agent. However, there are about 500 more artists that only exist on Last.fm; they’re more underground and are not yet on Musicbrainz or Allmusic.

@OttoKerner Are you certain that the newer ‘Plex Music’ agent pulls from Last.fm? If so, it doesn’t work. It won’t even match during a manual ‘Match…’ search attempt.

The primary source is Musicbrainz. Only some supplementary data are filled in from last.fm

Okay so if the artist doesn’t exist in Musicbrainz to start, it won’t then look to Last.fm for a match? Is there any other way to do this? Approximately 15% of my library is unmatched because those artists only exist in Last.fm.

You can rely on embedded meta tags, which would at least give you proper album titles, cover art, and track titles, genres etc.

And/or you can create those artists on MB yourself.

Thank you for your tips. Wouldn’t it be useful for people to have the option to use both (MusicBrainz and Last.fm)? Utilizing the embedded metadata only may limit the strengths of Plex and Plexamp. Allowing matching of the artists who only exist in Last.fm, would reduce the metadata burden on the users, which is why there’s a matching system there in the first place, no?

As a user, it is not feasible to create 500+ artist records in Musicbrainz; it would also be redundant if we could simply match those artists with Last.fm records.
