Hey guys i drasticly need your help putting a play list together for a dance im djin any way they want a mix of 70's,top 40,hip hop and all the rest my biggest problem is the 70's so if you know any must play hits i could use please list them thank you

What you should get is the Promo Only Essential Series, it has music from 1995-1940, and is perfect for mixed gigs, where you need some retro, some OLD stuff, some Country, some Rock, etc.
You can view the disc listings at www.promoonly.ca, after you sign up to be an "insider".
If I were requested to play 70's style stuff, I'd play stuff from Grease, and disco stuff like Stayin' Alive and stuff.
Hope that helps!

Scully's dead on with the Promo Only series, but if you can't go that route, try these CDs: Pure Funk, Pure Disco, Pure Disco 2...or just go to to your local record shop and look for some good 70's compilations.

Or raid your parent's 8-tracks.
