The original idea for the background music for "Sapience" (the village with some RPG spoofs) was a not-so-relaxing piano song (should be playable at the top of this post). I'm trying to think back and remember why I chose to do this at first; the only memory I can dig up is that I wanted it to feel exaggerated and jokingly grand, like a big RPG, or something. It is supposed to loop, so the end builds up again for the beginning.
Fortunately, at around the same time, my friend nicknamed Rincewind allowed me to learn playing guitar with one of his old guitars. I whipped up quick covers of Marilyn Manson songs (Coma White, The Nobodies), then I proceeded to create a song from scratch, which ended up being the final background music.
Whenever I think back on this, I'm glad I got the guitar; the piano thing never felt right.
