This is a beautiful skin. Especially with the font you recommended. Excellent work, and thank you. :)
Would you be interested in making a slight variation without the rounded border? Here's an example.
(I literally just removed the border.)Edit:
I also noticed a tiny bug: when ratings are displayed in the Artwork view, the stars are still yellow, rather than gray.
Seriously, gorgeous skin. I might use this to get some of my friends off iTunes at last.
