Hi there!  So here it is:)  
Let me know... yada yada...! 
Have fun!

I'm llguitar on Instagram - http://instagram.com/llguitar Follow me :)

**UPDATE**
Taylor plays this with the the Capo on 6.  
http://www.youtube.com/watch?v=v7PNRKpMYKQ

So, if you want to play like her, then
click the transpose down arrow 2 times (-2) 
and the chords become C G Am F. Make sure to put
the capo on the 6th fret!

*Note- Taylor plays the G as [320010]; A regular G 
works just fine though :) 

This version (capo on 4) still plays right along 
with the CD or her live, so you don't have to 
transpose if you don't want to;)   Have fun!!!

Without me, without me, without meeeee

Realize the blame is on me

Pretends he doesn't know, that he's the reason why
       Bm                                G 
You're drowning, you're drowning, you're drowning-e-e-e-ing

And I heard you moved on, from whispers on the street
  A
A new notch in your belt, is all I'll ever be
    Bm                    G                D
