Felix Da Housecat never met a trend he didn't want to shack up with. Thanks to its churning guitar and hi-hat clatter on the downbeat, "Tweak!" rocks and stomps. But mostly it sucks call it the house of a jealous producer. We're supposed to marvel at this endlessly tweaked mosquitolike synth line, but for all of its passé irritation, the title might as well refer to crystal meth. Poppers are more fun than this.
