So last weekend (and this weekend too) in Miami has been the Ultra Music Festival with a fuckton of Electronic artists performing. They streamed the whole thing live last weekend (and will do it again this Fri/Sat/Sun). This page is keeping a running list of all the DJs sets as well as tracklists so you can track down the individual songs:

Some BAMF stuffs on there. Not all dubstep. Have been hitting play and letting it play as I do stuff. Most of the mixes are downloadable too if you want the whole mp3.
