It is in Europe. I am a fan of Mazzy Star and play their music in Denmark or the UK.
This is simply false.
Yes it is. If it's not available for you then blame the fucktard lawyers who made the call that it should not be available wherever you are for some dumbfuck reason. Spotify is not responsible for this, they just comply with the aforementioned fucktard lawyers.
Their point is at a higher level than a single artist's inclusion. What you're advocating is for artists to give up their rights (whether primarily or indirectly negotiated). "Just do what the lawyers say."
I didn't think Spotify had fanboy/fangirl followings, but based on your and others' comments, I stand corrected. What do I know!
I fully support artists to decide what they want to do with their music, but artists who sign contracts with labels and music companies do give up their rights, like it or not, that's how it works. And yes, Spotify enforces contracts and geographical licensing deals that dumbfuck lawyers invent because reasons. What would you want them to do, break IP laws?
