Katy Perry feat Juicy J - Dark Horse (CCMC Remixes)
This is not an official single yet as it is from her iTunes countdown, however, there are some club mixes by Country Club Martini Crew. The slow groover has been turned into a hot floorfiller. The big room Electro House mixes change up the vibe of the original which was more laidback. All of the vocals including Juicy J's rap are incorporated into the main versions. Only the Extended version skips the second verse, though the Full Vocal version and edit have them all. These are really awesome.
