Heh, no worries. Yes, the music is all fair game. The only requirement is that you add a credit in your game attributing me as creating the music.
Edit: For anyone else, I have a bunch of techno-ish music
available here that is under Creative Commons that you can use for any of your projects. So if you need some music (or even just some placeholder stuff) feel free to leverage it. Or if you just like the music, you can just download it to listen to. Whatever works. :)
