Is it possible to further develop the integration Plex already has with Last.fm to allow “Love” ratings for songs to be synced with a Plex Library? Plexamp already has a “Loved” playlist, so this integration would work nicely for those of us who want to switch to Plexamp as a primary music player but want to have their last.fm loved songs synced.
The workflow could be similar to MusicBee’s, where the user manually runs a “Sync Last.fm Loved Tracks” job, or you could configure Plex to automatically run the job on a given interval.
If this isn’t possible, maybe Plex can read the “LOVE RATING” ID3 tag. That way, users can sync the last.fm love status using MusicBee, and have Plex read the “LOVE RATING” tag that MusicBee sets.
