I have only one online/offline device that a use to enjoy Spotify. In my list of offline devices there are three of them. Obviously they are the same device, my Android, in different update times. 1) My question is, would I lose all my downloaded music from my cellphone if I removed the two older updates? (i know i could discover it myself by doing it, but i really don't want to re-sync).
2) And, is giving permission to last.fm and musixmatch knowing what I'm listening to, the same thing as getting another two offline devices?
