I figured out how to play the Rock.ogg loop on guitar :3 I was not quite sure if this would go in Creativity, Off Topic or General Discussion, but I chose General Discussion for now and it can be moved if needed.
This is super easy to play on guitar. It's in Drop D tuning (DADGe) and consists of regular power chords.
