I have been extremely fortunate in the department of musicians, I've always been able to find great musicians who work for free. It makes me a bit uncomfortable that I can't pay them at this point, but it happens. But, I have never had an issue with a musician that has ripped tracks, I didn't realize that was a thing, unless the musician you're hiring is Vanilla Ice. The irony of the situation is that I'm a musician myself, and these people have sought me out. The only reason I work with them is because that's one less headache I have to deal with, and I know they do great work.
Your game looks adorable. My project is currently giving me a lot of design headaches, I don't suppose you'd be willing to let me give the music a go. If you like it, you can use it, if not, I can see about sending some of my contacts your way.
