Looking For Name Of Song

I heard this song on the radio many times over the summer but have not beed able to find out what the name of the song is. Here is song of the lyrics that I remember hereing in it...

"Since you've been gone I'll leave the porch light on"
(In the background you here girls go "mmmm bop bop bop")

I'm guessing that it's style is like an alternative pop. It's a male singer and I think it was a new song that came out during this summer some time.
