I can't seem to find a proper answer for this, so hey--I finally got around to watching the HD DVD of Miami Vice this morning, and I found I really liked what comes closest to a main theme--the music that plays during the opening credits and at the end of the ending credits.

What the heck is it?  The closest reference I've been able to find is to a remix of a song on the soundtrack (Moby's Anthem, specifically the "Cinematic Version"), but I can't quite find confirmation on it...

IMDB lists a John Murphy for what little instrumental underscore there was in this thing, if that's helpful at all.
