afford yourself some classic from time to time..
then suprise the crowd - among bunch of new stuff spin some older track that will fit ;)

remember, there will always be kidz on the floor that arent so much in touch with latest music OR those who just start partying, so they dont know they missed - show them..

I started visiting parties in 94.. but I wouldnt mind if I'll hear few classics this weekend in club.. like old mills stuff..or something from clarke's archive one.. or inigo's the secondary.. or planetary assault system on peacefrog etc etc.. why? cause I'm going out to have fun, not only listening the new stuff..

and if you are making some promo mix, you can put also some older stuff, but keep it in just for a while, or play with it in some part of the mix..

so what if somebody comes with "been that before" attitude, does that makes him better in any way? I dont think so..

at the end of the day, its your call ;)
