Looks good so far!
Arsenic with mineral arsenic+cubism filter background
a few things I noticed:
If number of tracks is not enough to go past the bottom of 'below artwork' text, than it is not refreshed after scrolling
HeaderBar and Panel Header is transparent but Panel ChildHeader is translucent. I think it would be better if they were consistent.
Background of column browser header (in vertical arrangement) sometimes picks up weird artifacts (as if it's actually getting the background from a different area) when switching between tabs.
Visualiser: spectrum (especially when in main panel) gets the solid background re-painted when switching between tabs.

Also, would it be possible to have the shadow effect on the overlaid text, as per compact player?
and lastly (for the moment
)
have MB remeber the last folder used for the background images.
