Chords used: D,A,Em,G i', a bit unsure on the ending of the chorus, the 'but when i got home' part, but
apart from that i think that it sounds prety much spot on! :) enjoy!!! 
D,A,Em,G x2
 
DAEmG I was riding shotgun with my hair undone in the front seat of his car
DEm He’s got a one-hand feel on the steering wheel
GA The other on my heart
DEm I look around, turn the radio down
GA He says baby is something wrong?
DEmGA I say nothing I was just thinking how we don’t have a song
N.C And he says...
 
DEm Our song is the slamming screen door,
GA Sneakin’ out late, tapping on your window
DEmG When you’re on the phone and you talk real slow
AD Cause it’s late and your mama don’t know
Em Our song is the way you laugh
GA The first date “man, I didn’t kiss her, but I should have”
EmGEm And when I got home ... before I said amen
GA Asking God if he could play it again
 
D Em G A
DEmGA I was walking up the front porch steps after everything the day
DEm Had gone all wrong or been trampled on
GA And lost and thrown a-waaay
DEmGA Got to the hallway, well on my way to my lovin’ bed
DEm I almost didn’t notice all the roses
GA And the note that said...
 
DEm Our song is the slamming screen door,
GA Sneakin’ out late, tapping on your window
DEmG When you’re on the phone and you talk real slow
AD Cause it’s late and your mama don’t know
Em Our song is the way you laugh
GA The first date “man, I didn’t kiss her, but I should have”
EmGEm And when I got home ... before I said amen
GA Asking God if he could play it again
 
D Em G A Da da da da
D Em G A
EmG I’ve heard every album, listened to the radio
DAEm Waited for something to come along
G That was as good as our song
 
DEm Cause our song is the slamming screen door
GAD Sneaking out late, tapping on his window
EmG When we’re on the phone and he talks real slow
AD Cause it’s late and his mama don’t know
Em Our song is the way he laughs
GA The first date “man, I didn’t kiss him, and I could have”
EmGEm And when I got home ... before I said amen
GAD Em G A Asking God if he could play it again...
D Em G AD Em G A Play it again... oh o yea o yea yea
 
DEm I was riding shotgun with my hair undone
GA In the front seat of his car
DEm I, grabbed a pen and an old napkin
G
