Sorry if this question has been asked before, but I found it to be a very neat and nice feature, where you could upload some of your favorite songs. As a music lover, that was just perfect to me, so I can share my love for music with the world.
Unfortunately, I was going to try them, but their music selection is really limited. Half of my more obscure songs aren't even there, and since I don't have permission to upload songs, I'd rather stay away from that feature. Does last.fm or any other huge music site have embedded playlist features?
