I heard this song while working at Victoria's Secret- MARCH 2012 playlist

Hey guys,
I was working the other day at VS and I heard a song come on, and I've been trying to figure out what the song is or who sings it. It starts out slow with a girl singing it, she kind of sounds like Jessica Simpson in the beginning but then later in the song, she sounds like Taylor Swift and the music gets more upbeat. I can't think of the lyrics at all.

Does anyone who works there now know what song I'm talking about??

Does anyone who currently works at Victoria's secret know any of the songs that are currently being played in the stores?

The only one I can think of right now is Stutter- Maroon 5
