I've been using spotify for quite some time now and generally i'm content and happy. I've got used to some music missing, for example if there's a greatest hits record released often the albums before are not complete or even gone. Or unknown obscure musik might not be avaliable at all. Ok ok i can live with that.
What's really annoying is when essential artists are unavaliable but i get a sh*tload of more or less crappy "a tribute to xxxxx" . Now i looked for Tool albums and found none, same with King Crimson, not a single original song. But a bunch of cover albums. Since they are covered there should be a market and listeners. i dont get it.
Why? Can i somewhere make a wish for missing music? Or are you analyzing the failed searches?
