As a dj I've always organized my bags from a BPM starting point... so it goes from anywhere around 128-130 'till 160 give or take a few bpms...

I start from the slowest and move upwards & onwards... moving the crowd in waves (when I get' em moving that is :P ) of hard, funky, minimal, etc... I find that if I play 2 hard evry1 gets tired and looks down, I prefer the smile so when it gets 2 much I slowly shift 2 the chicagoish getho thing, then bring back the pounding stuff later, etc... finish around 160...

My 2 cents,
