Okay, so I just figured out this song with a little help of her http://
www.youtube.com/watch?v=w6Ei4_LE-Q4 . she has covers of almost all the song of Big 
Time Rush, and she's kinda great! but she doesn't post the chords of the songs :/ 
anyways here is what I ended up with

Chords:
E: 022100
A: 002220
C#m: 446654
B: 224442
