Good chiptune music?

[Swords_to_Plowshares]

I highly enjoyed the music in VVVVVV, a retro-style platformer. If you liked it too, you can get the soundtrack for a $4 donation here.

Anyways, is there any other high quality chiptune music out there that would be roughly on par or better than the VVVVVV soundtrack?

As for actual game music, the Earthbound soundtrack is incredible for being 16 bit.
