Take note that the distortion is deliberate, it's supposed to sound that rough. I was going for a retro chiptune-ish sound here without taking it too far, and I think I did a good job. If I'm right, you should be able to listen to this entire track without really paying much attention. Consider it 'in the background' music with a happy vibe to it.
Please contact me if you would like to use this in a project. We can discuss the details.
