some title cleanup might be needed? especially stuff like "[FREE DL IN DESCRIPTION]", which is quite common
GTIN and ISRC are optional metadata
playlists and albums are both implemented as "sets", and perhaps both should be importable? I know a lot of artists don't properly set the type for what's pretty clearly an album (even Taylor Swift has some such examples)
Creative Commons Licenses should be detected and added when present
track downloads are optional and should be detected (sometimes with a Buy link that goes to a file hosting service like MediaFire or MEGA, or with a DL LINK IN DESCRIPTION)
I know it's mentioned in #5, but I figured I'd start up a ticket with a link to the API docs at least~
