Music: unexpected = better?

I was playing with more of the footage of Edgar this weekend and trying to challenge myself to get the music sounding right, feeling right. I think it's going to be an interesting stretch for me creatively to try to write music for soundtracks...I'm used to writing music by itself, to stand alone. This presents new cool questions. But my first attempt totally sucked.

My second attempt was a bit luckier, but only because it was lucky...Then I played it for Andrea and she made an interesting point: Lots of times when you see movies/documentaries about Latinos, all the music is some Mariachi south-of-the-border stuff, or Salsa, or mistakenly Flamenco. (European music? Cough, cough.) So to have music that's utterly different from those styles (and mine's utterly different) is unexpected and can catch viewers' attention.

I was happy to hear this, as I'd been wondering, "Should I be hunting up some public domain Mariachi music?"

The music I know how to make on a computer—which, so far, is the only tool we can use to get notes onto film—is heavily influenced by J Dilla. Deep jazz hip-hop/techno? Is my shit going to fit? If so...Cool.
