I did an "8bit" cover of Guitar vs Piano by Goukisan.
I say "8bit" because it's really only the leads that have been changed to Gameboy sounds.
I couldn't find a decent 8bit percussion sound to do the song justice. So I left it as it is.

A huge thank you to Goukisan for allowing me to upload it :)

Go have a listen.
I'm off for a shower.
