Definitely varies by DJ. The other DJ I like plays a lot of R&B as well as the "classic" WCS songs (The Game of Love, which one can CC to). I play a lot of 80's songs and more modern stuff (Usher, Britney, Outkast, 50 cent) but I am getting back to more classic R&B stuff. I'll definitely play CC, H, salsa, and merengue, though most of the other DJ's that work one of the local clubs on Westie night won't. (Of course, I am more a ballroom DJ than I am a pure swing or pure salsa DJ, so I will not hesitate to play waltzes or quicksteps/foxtrots that can double as swings.)
