Gym Class Heroes?

Question

I love this song by gym class heroes. The song i thought was called Cupid's Chokehold, but I can't find it on iTunes. Is there another name for this song? Why can't I find it on iTunes?:

Ba ba da da
Ba ba da da
Ba ba da da
Take a look at my girlfriend
She's the only one i got
Not much of a girlfriend
I never seem to get a lot
It's been some time since we last spoke
This is gonna sound like a bad joke
But momma i fell in love again
It's safe to say i have a new girlfriend
And i know it sounds so old
But cupid got me in a chokehold
And i'm afraid i might give in
Towels on the mat my white flag is wavin'
I mean she even cooks me pancakes
And alka seltzer when my tummy aches
If that ain't love then i don't know what love is
We even got a secret handshake
And she loves the music that my band makes
I know i'm young but if i had to choose her or the sun
I'd be one nocturnal son of a gun
Take a look at my girlfriend
She's the only one i got
Not much of a girlfriend
