Do you have raw play events, or do you have progress events as well?
The single biggest improvement you can make with this kind of system
is to
quantify engagement somehow. Play starts are often a very poor
surrogate
for preference while more engaged events such as 30 second progress
can be
much better (or not, music consumption can be a bit strange).
No events, at least not for now.
I do however have a rather nice domain model to navigate:

(It's supposed to be an UML class diagram.)
I hope that some semi-sophisticated Album, Track and ArtistSimilarity
can be used to improve the results.
Perhaps it's a good idea to have Playlist, Album and Artist
implemented as Item too.
