Paul Taylor wrote about working on an indie game called Determinance, and he is exactly the kind of musician I would want to have working on any of my own games:
Each track, even the menu music and closing theme, is based around a core melody or chorus. This is something I believe in passionately – if you can’t whistle the tune of a song then it’s 99.9% likely to be worthless.
Wouldn’t you want a person who is passionate about what he does making your games?
