I won't be able to compensate you though, it is afterall a free LD compo jam game.
Mooch:This game was already being developed before the Kickstarter began, at which point I was asked to do at least two tracks. I made three (title, battle, exploration ambience). This is my first commissioned work, so when the developer asked me what I thought was a fair price, I really had to think about it. How much? Would I charge per minute? Or per tune? Then when I finally thought I had a decent price, he offered something higher (so apparently my offer was on the low end, or he thought it was worth more than I offered, or both!). I will be basing my price off of that from now on (as a fixed per-minute price).
