Perfect pop songs are normally the purview of the three-minute and under crowd. So Atlanta based girlpuppy’s (aka Becca Harvey) “Destroyer” clocking in well over the five-minute mark is decidedly out of bounds. It’s also every bit the perfect pop song and one of the best on offer this year. The song’s driving rhythm effortlessly shifts from first, to second, to a drum driven third gear and never lets go. Harvey is at her offbeat best on her debut LP, When I’m Alone, when her songs have a little more spring in their step and something unusual to say.
