also keep in mind how often a crowd gets to hear those dj's. With pvd making the trip to oz only once per year, he's expected to play the tunes he's known for, esp for an angel. Now if he was to do that to the same crowds he plays to several times a year, it would get dull really fast.
I would much prefer they play a few classic mixes rather than crap new mixes of great older tracks. Basically i wish someone would stop fingers burnt from screwing over anything else.

What I wouldn't do to hear shit like Leaving Town, or Red Zone (part 3) or Song For Life.

too many classics wont hurt

I understand what you mean (anyone could spin classics, but the top-flight should play the most exclusive stuff) but there are songs which people just attached too.

A good ratio for me personally is 1 classic for every 8-10 newer songs.
