Skrillex is a magician. His trick is turning the elusively thwump­ing U.K. dance music called dubstep into high-fiving dance-floor heavy metal. The DJ-producer's latest EP suggests new artistic pretension with an "orchestral suite" and a woozy jam stuffed with Doors references. But for the most part, the 23-year-old's bass-­crushing, hyperpaced populism is undiluted, from the bomb-drop arena funk of "The Devil's Den" to the screwball hip-hop breakdown on "Right on Time" to the laser-­blasting inanity of the title track, which ends with someone bragging, "I'm eating Fun Dip right now/Not givin' a fuck." Not a bad credo for music that makes a disco sugar high feel downright pornographic.

“My President”

Young Jeezy teams up with Nas on this track, in which he compare his own success with the idea of an African-American winning the Democratic Party's nomination in the 2008 presidential election. "When I pulled up in my car, that s--- was unbelievable to people in my neighborhood because they were like, 'We grew up with him. How the hell did he accomplish this?'" he told Rolling Stone. "I feel like it was the same way with Obama. I grew up all this time, but I've never seen a black man this close to running this country."
