Maybe Calvin Harris is celebrating being named the fourth top-earning person under 30, raking in a cool $46 million, but he's dropped this preview of his remix of "Eat Sleep Rave Repeat," which sounds exactly like the kind of anthem that will have bootleg t-shirts done up by summer's end. You have to love the acid sounds Calvin embedded in this track; at its core its a huge house beast, but those throwback acid elements give this one a bit more depth, and a bit more of that old school rave appeal.
