(Chorus)
This is my heartbeat song n' I'm gon' play it
Been so long I forgot how to turn it 
Up up up up all night long
Oh, up up up all night long
This is my heartbeat song and I'm gonna play it
Turned it on but I know you can take it up
Up up up all night long
Oh, up up all night long.

(Verse)
You... where the hell did ya come from?!
Ya were a different, different kind of fun
N' still used to feel it now
Now, I got pins n' needles on my tongue
Anticipatin' what's to come
Like a finga on a loaded gun
I can feel it risin', temperature inside me
Haven't felt it for a long time

(Chorus x2)
This is my heartbeat song n' I'm gon' play it
Been so long I forgot how to turn it 
Up up up up all night long
Oh, up up all night long
This is my heartbeat song and I'm gonna play it
Turned it on but I know you can take it up
Up up up all night long
Oh, up up all night long.

(Verse 2)
I... I wasn't even gon' go out
But I never would have had a doubt
If I don't know where I'd be now
Yo hands on my hips n' my kiss on yo lips
And I could do this fo' a long time

(Chorus x2)
This is my heartbeat song n' I'm gon' play it
Been so long I forgot how to turn it 
Up up up up all night long
Oh, up up all night long
This is my heartbeat song and I'm gonna play it
Turned it on but I know you can take it up
Up up up all night long
Oh, up up all night long.

(Bridge)
Until tonight I only dreamed about ya
I can't believe I'll eva breathe without ya
Baby, ya make me feel alive n' brand new
Bring it one mo' time, one mo' time

(Chorus x4)
This is my heartbeat song n' I'm gon' play it
Been so long I forgot how to turn it 
Up up up up all night long
Oh, up up all night long
This is my heartbeat song and I'm gonna play it
Turned it on but I know you can take it up
Up up up all night long
Oh, up up all night long.
