This is my first tabs so please tell me what you think! Not really a Justin Bieber 
fan but it's a catchy song. I believe it's right the other versions doesn't sound 
right to me. I recommend playing these chords as bar chords.



 
F           Dm7                  Am       G 
Show you off, tonight I wanna show you off
F           Dm7                  Am       G
What you got, a billion could've never bought

F                       Dm7
We gonna party like its 3012 tonight
Am                        G
I want to show you all the finer things in life
F                        Dm7
So just forget about the world we young tonight
Am                 
I'm coming for ya, i'm coming for ya

(You should finger pick the chorus) 

      F        Dm7      Am

     G              F
Is a beauty and the beat
         Dm7                 Am    G
Who can make my life compleeeeeete
     F         Dm7           Am

        G                 F
