I had too much time a while ago and did a quick mockup of what i find, would be an improvement to the spotify experience under mac os x. I didn't take a closer look at the spotify web-player nor did i study spotify on other platforms. i just scribbled down what i would like to have and what would improve spotify for me at this very moment. i don't consider this a real thought through design for a new spotify app, but i wanted to share my ideas with you. perhaps it'll start some kind of discussion/conversation, or not.
however, thanks for this brilliant service.
