I usually find a midi of it. Open that in jammer from www.soundtrek.com and select a couple of rhythm tracks then tell Jammer to build a progression based on that.
Doing that, gives me the basic pattern, what key it is in, and tempo.
I then listo the midi and enter where all the section changes occure as it plays.
I them mute all the midi files, and stat telling jammer what band styles I want and when I get to the end, hit compose and listen a few times, after which a change any chords i feel it wants and when i am happy with it, i record a sing and suck over it and listo that to see if I like it.
If I want something more than the basic chord progression, when starting, I select one, maybe two melody or harmony tracks of the midi, and maybe an extra rhythm track, and tell it to build a progression out of that.
The more you select, the more complex the progression wil be.
They can get real scary sometimes i tell ya, but sure do come out woith a lot of stuff i find interesting anyway.
