It's a shame cos imho most of the records mentioned in this thread are great (with the odd exception 'cough' Pioneers )
The problem is, when you look at the dance floor it's usually packed when one of these is playing, so it's difficult to blame the DJ!
What bothers me personally, is when they are trotted out one after another! To me, that's the DJ just being lazy! In a dance floor driven scene, they are always going to be needed to pep up a dance floor BUT that's when the DJ should be looking to play summat different once he's/she's got them up!
So, to me, hearing one or two 'overplayed' oldies in a set is no biggie as long as it's balanced with something semi-known, different or simply 'underplayed'
btw Just got what i consider to be a future 'overplayed' 70's classic!!!!!!!!!!!! Don't know much about it at the mo' as it's unreleased and I have no idea who it is etc BUT after a number of plays, i'm convinced it's gonna be a biggun and (hopefully) one everyone will be moaning about hearing all the time in the future
Cheers
