All you need is me
You're a loser if you need your head up,
Just come to me and I'll give you what you need.
It's your problem if you gotta worry,
Take your troubles to me and I'll give you some of this.
Oh yeah, all you need is me.
Yeah, yeah, yeah.
You can dance, dance, dance.
All night long, all you need is me.
Oh yeah, oh yeah.
Everybody loves me.
Oh yeah, they just don't know me yet.
You're so sweet, you make my heart go flip,
Take my hand and we'll go 'head together.
Oh yeah, all you need is me.
Yeah, yeah, yeah.
You can dance, dance, dance.
All night long, all you need is me.
Oh yeah, oh yeah.
Lips so lush and they say: 'Bieber, we love you!'
We in this together like MacDonald's!
Oh yeah, all you need is me.
Yeah, yeah, yeah.
Oh yeah, oh yeah.
I ain't never been on a big scheme.
No wonder I am me!
You're gonna know me when I become the American Idol!
And if they can see me now. (Yeah!)
Come on, give it up for your hero! (For Bieber!)
Ooh-ooh ooh-ooh-ooh ooh-ooh-ooh. (Woo-hoo!)
Oh yeah! All you need is me! (Ooh-ooh) Yeah!
