If it still gave you flac files like Bandcamp does, I'd say that that's strictly better than both bandcamp and spotify and would probably use it. The main thing for me is the selection of music available - Any artist that's on there should have their entire discography available and in flac. The second thing is price. I'm not going to pay $10 for an album anymore unless it's literally not available elsewhere. Otherwise, I'm just going to torrent things. ------ My music-related idea is something that keeps track of what music you have already, and tells you if you're missing any albums/eps/etc from an artist (particularly, new releases - but older ones too). I've been making a script that fetches a list from Musicbrainz and you tell it what releases you have, and it'll output which ones you're missing, but the way you tell it is setting a number in a database. It'd be nice if there was a program that did this for you instead.
