I'm not sure if this idea has been posted or not but I think there needs to be better benefits of being a paid subscriber. There aren't many differences between free and paid. When Taylor Swift pulled her music from Spotify and the last Black Keys album is still not available it is clear that some artists don't want people listening to their music for free. I think the paid subscribers should be able to have access to exclusive content that is only available if you pay. Maybe artists will then be more open-minded to allowing new albums on Spotify and maybe Spotify will gain more paid users.
Hey there and thanks for the feedback!
