I don't use last.fm, but wtf? How is there a better way to find music, efficiency aside? I guess to be fair there isn't anything wrong with using last.fm but to me it just feels like cheating. Every artist is spoon fed to you by your previous selections of music. It's like "Hey, you like this band, well you MUST like this band." Last.fm is good if you just want to listen to the same sounding stuff over and over again. For me, I look up artists on Wikipedia to see who they collaborated with, who their producer was, who else that producer has produced, and maybe I'll find a new artist that I like. I guess I just find music my own convoluted way.
