I've been thinkin' 'bout you
Wondering who's stuck in your head at night
Wonder if I ever cross your mind
Keeping you up in your bed at night
I've been thinkin' 'bout you
I can't get you off the brain
Loving you is something strange
Don't get me wrong
I ain't complainin'
I've been thinkin' 'bout you
I'm wondering if your love is a game
Just kissing girls and taking names
Is it love or entertainment
I've been thinkin' 'bout you
Wondering who's stuck in your head at night
Wonder if I ever cross your mind
Keeping you up in your bed at night
I've been thinkin' 'bout you
I try to fight it but it's hard to hide
I've been thinkin' 'bout you
I've been thinkin' 'bout you
I've been thinkin' 'bout you
You are a habit hard to break
You are more than a heart can take
There's no exit no escapin'
I've been thinkin' 'bout you
Maybe you are my destiny
Or maybe just a fantasy
Maybe it's just my imagination
Boy I've been thinkin' 'bout you
Wondering who's stuck in your head at night
Wonder if I ever cross your mind
Keeping you up in your bed at night
I've been thinkin' 'bout you
I try to fight it but it's hard to hide
I've been thinkin' 'bout you
I've been thinkin' 'bout you
Early in the mornin'
Think about you all day
Late night in the evenin'
I can't get you off of my brain
Early in the mornin'
Think about you all day
Late night in the evenin'
I can't get you off of my brain
I've been thinkin' 'bout you
I've been thinkin' 'bout you
