So, i've been asked to DJ my friends wedding social, Me being a club DJ i don't really know much of old school hip hop, and also what are the usual "social songs"

If anyone has a few they can throw at me that i can work into my set that'd be greatly appreciated!

Tribe Called Quest - Award Tour
Digable Planets - Creamy Spies or Blowing Down (Anything off Blow Out Comb)
Warren G - Regulators
Slick Rick - Childrens Story
Beastie Boys - Check your head + Ill Communication
Black Sheep - The Choice is Yours
