Aeropostale....

But it was in one of the Canadian stores. I heard the song before, i think it used to be popular so i don't think the location will matter :\

But it was sort of like a pop/rock type of song with a female singer. It sounded like it might've been mainstream before, and her voice sounded...rocker type. I just could catch the lyrics from the course but after searching it might be a little different.

it went: "No I can't take it [...........] (near end of course) ...i want to love you, can't stop thinking of you"

something along those lines :\ that's all i have though. and its not the all american rejects or tegan and sara. it seems like only a few years old too, maybe around 2 years old.
