Music.app is already better than Spotify at handling the relevant metadata. But the dedicated Apple Music Classical app is roughly the same as IDAGIO.
(They bought IDAGIO's former competitor Primephonic to do it)
For each composer, it shows all their well known works, and then you can tap on each to see all the recordings of that particular piece.
Smart move on Apple’s part, if you ask me.
And the play history integrates with the main Music app
this is a problem for classical (and jazz) for two reasons a) these genres are not particularly popular on the platform so there are few unique users and b) the songs are LONG so listening sessions contain fewer songs.
track cooccurance based recs work well for popular genres, but these other genres need a different approach to recs and that's actually where AI could do really well by digging into the unstructured data associated with the tracks (sonic analysis of the song, biographical information about the composer, details about featured soloists, etc) rather than relying on piles of user behavior.
