Minor nitpick, but what's up with the artifacting on your large images? See the text in your image "the button at the bottom of the page." See also the gradient in your second image: "Create a Private Playlist" There are noticeable artifacts, whether from compression or something else. It just takes away from that polished feel for me. Sorry I don't have actual functionality feedback!
