Tricked by my iPod.
I went looking for Mickey Factz "Heartbeat"... and got Scouting for Girls "Heartbeat" instead.
Which wasn't what I wanted, but was actually pretty good in its own way. Serendipity.
Neither's on iTunes, but here are some ghetto deep links.
(Oh, and while I'm here? Apart from bands, MySpace is so 2005. Get a Facebook, would you?)
