Solid no-frill brostep two-tracker from Dub Police. While Doctor P keeps his track relatively balanced and melodic, Trolley Snatcha aims directly at the dancefloor with a gritty and dirty track that has all the elements to get quite a lot of airplay this season. The whole thing is heavy, it's got the "massive" bassline and it's made to make you dance. Classic, not extremely original, but very efficient, which is pretty much all I was asking for.
