sorry just one more thing too say. i constantly hear people saying that music over a certain b.p.m (usually around the 135 mark) starts to become druggy.
This could not be further from the truth i reckon cuz i surely can't imagine all the old people and little kids being ****ed up on drugs dancing while the Brazilian band was playin at a crackin 150 - 160 b.p.m range.

I think an experience like this can change the way u think when producing music. I'll leave now.
