I'm with you on the Burnout issue, but I have to say, I don't know how much of a selling point music is for handheld games, even in the case of Reset Generation. They definitely add to the experience and can make a good game even better, but from a development point of view, a soundtrack scored by a hand picked counter-culture artist is a bit of a luxury and most studios will probably be more inclined to spend resources on making their game look better.
Unless you have the sort of development budget that Reset Generation had, putting the necessary research and money into getting the right artist for the job (never mind finding one that will agree to do it) is pretty much impossible, at least in the mobile space. It would be great to see some of the bigger budget DS and PSP titles take a more forward thinking approach to this however. What about some sort of ambient score by Boards of Canada for fl0w or something, that'd definitely work I'd say.

Surrealism means you have two giraffes and the state requires you to take harmonica lessons.
