《Heartbeat》的歌詞如下：
女：
You make my heart beat
Like a superstar
You're my favorite song in the world
When you're around
男：
Every beat goes boom boom
Every time I see you girl
I can't help but lose control
My heart beats for you
女：
And every second counts
When you're around
And I just can't deny
My heart beats for you
男：
Every second that we share
Is like a dream come true
And I just gotta say
My heart beats for you
女：
You make my heart beat
Like a drum machine
And I don't even care
'Cause it's the only thing
That's on my mind tonight
男：
And every beat goes boom boom
Every time I see your smile
I can't help but fall in love again
My heart beats for you
Yeah!
合：
Every beat goes boom boom
Every time I see you girl
I can't help but lose control
My heart beats for you
Yeah!
Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah! Yeah!
