Need help finding a good download of this remix.?

I go out to the club and theres this remix of the "Ride-Ciara ft Ludacris" it plays the section "LUDA! She rides her like a rollercoaster" etc than it goes into like an upbeat electro section. Difficult to explain. it could just be a local DJ thing but if anyone knows what the heck im talking about gimme a post or link or something. thanks
