the three captions (seekbar, album list and pl dropdown) are not very nice.
Black on grey is not very readable for your track info panel, a light grey would be nicer I think
You can change the background of pl dropdown to fit your whole layout
And I don't use album list, but with no vertical scrollbar it would be even nicer
I don't mean to criticize you, but I think those small things could improve your foobar
