You may want to increase the contrast on both the top text and the bottom buttons. They blend into the background a bit much. The top part of the top bar should also be a little darker silver to match the menu button better.
Good call on adding more rows to the queue area. I can't decide if it's better to have it like you do or white with black text. Both would work. Is it possible to do a quick mock up of that?
Overall the skin really looks great. And you're fast too!
EDIT: Oh, your original post has a white song list in it. I've got to say I like that look better, it goes much better with the skin since the black area would be so large.
