Yup, totally agree. The back button issue alone is incredibly annoying. I also wish they would just give me my entire history—there are many things I've listened to that I really liked, but since I didn't add them to my library and don't remember the names, they're lost forever. It just seems incredibly stupid to me. I mean, what would it take to store a user's listening history? It could even just be a history of (unique) Artist names, for all I care; that would at least allow me to find the specific track or album I wanted to hear again.
