FOREVER 21 SOUNDTRACK i have no idea what this song is

Ive seriously heard this song a million times but no one knows what it is! its stuck in everyones heads it goes:
" what did I believe in What did I believe in"
and its in acuostic guitars, it sounds like 2-3 guys singing at once in an upbeat manner. Can you help me out please?
I tried google and the hype machine and limewire...no luck

Is it “Scarecrows in the Rain” by the Mystery Jets?
