Freestyle/drill team music?

Me and my friend want to start english drill riding together. We created a pattern this morning, but now we are looking for ideas for music? What do you guys like to listen to? What are the popular choices? We usually go trail riding to get to a HUGE open field (powerlines), and we were starting drill riding last saturday for fun. Now we want to put together a routine that is set to music and we will go practice it out in the open field every weekend. Do you guys know of some freestyle dressage tests set to music? We like pop music like Rhianna, flo rida, sean kingston, T.I., ect. Doesn't have to be by them, just giving you some ideas of the artists we like. Please include song name/writer or just the song name :)
