We need this redone. (At least) 3 band members of Pentatonix like guys, so why shouldn't it be redone to:

This boy's got me falling in love
And out of my mind
My heart is racing I'm out of breath
And I'm wasting my time
He's looking at me like he's never seen me
Running around his head
Oh yeah
So will you dance with me
Or do I have to show you how to love instead

It was released before Mitch and Scott came out, so it isn't like they need to hide anything anymore. Also, Mitch sings lead, so it's even more justified to change it.
