It's easy as hell to produce dance music, and with that accessibility comes a cavalcade of producers dropping tracks in a number of genres. Some producers and DJs are a "sure thing" - you'll pretty much know what to expect from these acts when you they hit the decks, or get a huge release on a smart label.
