Bit touchy today are we?, not taking the piss at all, i'm not a dj and don't want to be one so I have no idea of the average record numbers, but as i said in my post my mate started learning 18 months ago, NOT 10 fucking years + like the guys you mentioned so i thought 500 was rather impressive.
I guess my point of comparison is a lot of the popular k'rd dj' play the same shit week in, week out and i'd be surprised if a lot of them had more than 500, thats why I asked the question.
