While competition is the backbone of capitalism...
I should mention this freeware application :
Lots of GUI skins to change the look -
does almost all of the things you'd expect of a itunes controller.
...and did I mention freeware ?
This should have a free demo and be Universal. Please developer, if you can write an app like this you can click a few buttons and make this Universal. And since this is a $5 product it should certainly have at least a limited demo for $5 less. IMO.
