When it's just me and some apps, I'm writing the background track in an evening after coding the game earlier in the day. If I bring someone else in, now I'm writing contracts (something I'm completely unprepared to do correctly myself, as a non-lawyer). It's too big of a jump for a one-day zero-budget hobby game that isn't very good and only my friends will play. Not when I can quickly cook up something myself using readily available tools.
For a more serious project with a budget, absolutely you find a professional producer, just like you get professional coders and artists. But this isn't that.
