Yo, you need to be bump-in on the dance floor tonight, and what better to do that to then some good old hip hop and rap. Basically to make people dance you need something with a dam good rhythm between your ears to your feet. So what are some of the things you need? Well to name a few off the top of my head:

Got Money- Lil Wayne
I Feel like Dying- Lil Wayne
Lollypop- Lil Wayne
Do It To It - Cherish
Girlfriend - Avril Lavigne
Feel Good Inc. - Gorillaz
Hey Ya - Outkast
Get Ur Freak On - Missy Elliott
SOS - Rihanna
We Be Burnin' - Sean Paul
Promiscuous - Nelly Furtado
Don't Cha - Pussycat Dolls
Milkshake - Kelis
I Think They Like Me - Dem Franchise Boyz
Right Thurr - Chingy
Gold Digger - Kanye West
Run It - Chris Brown
This Is Why I'm Hot - Mims
Party Like A Rock Star - Shop Boyz

And those are only ones I can think of now, there are more and better mixes but thats a pretty good one there! Lil Wayne is at the tops of the charts and in high demand now, the week of June 10th his new CD sold 1million copies and growing!
Hope you find this helpful!
