Pandora might already have similar infrastructure in place, if it’s still used. It’s just not exposed to the public. Once upon a time, actual human beings used to import CDs into the service and tag the songs with different descriptors. This was to help the recommendation engine build playlists around similar music. You could see some of these tags when you chose “why this song” during playback.
One thing I wish the recommendation engines took into account was the record producer. Usually when you find a song/artist you like — you’ll find similar music by looking at other albums the same producer was involved in.
