And on parties all dj's push up the bpm. Mostly it's around 176-178, but some push it to 180 and more. It just gives a more party and dance feel to the beat.
Everyone is used to the 170-174 tempo, but when pushed up that tiny bit it makes sure you can't stand still
1993-1996 most tunes ranged from 150 to 170, with the top DJs playing said tunes a little faster. It was a few years later that they had been playing them to 180, when most tunes in the club circuit ranged 170-175 (of course some tunes were even faster e.g carlito & addiction, decoder & substance but again "exceptions don't make a rule)
as you said "most tunes in the club circuit ranged from 170-175" - so I don't really get what your point is...seems to me you are just trying to argue for the sake of it - and I'm not sure why you are fixating on the 180bpm either?
and if you want to be picky about numbers, well i said "nearly 20 years", 1993 was 22 years ago, therefore clearly not the date range I was talking about and arguably it was not what we consider to be drum and bass today
