I'm wondering if anyone has been listening to any music that pays homage to retrogaming. There's quite a bit out there.

Rymdeglage - 8-bit Trip is a song about NES and Commodore 64. The video uses Legos to represent pixel graphics.

mind.in.a.box - 8 Bits is a song from mind.in.a.box's latest album, which itself is a tribute album to Commodore 64.

There's also OCRemix, but I wanted to focus more on original tunes, and not remixes of actual gaming songs.
