This is cool. A few small thoughts:

- would love to be able to disable podcasts / anything non music related. it's my #1 gripe with the official Spotify client today.

- Winamp buttons shouldn't remain "pressed" in that play state

- Winamp doesn't like being stuck to one edge of the screen, after putting there and interacting it will often jump inward a bit

- Winamp could use the EQ in collapsed mode

- Would be nice for Winamp to remember its position (i think it grabs the NW corner of the large player every time?
