Here are the guitar chords for Top of the World.  
The other tab is totally correct but if you're a guy you'll find this song pretty high to sing.  
With the chords like this there is a lot more room to shift the capo down.  
I like playing it with the capo on 3 or 5, but the original song is capo 7.  

[ Tab from: http://www.guitaretab.com/d/dixie-chicks/130004.html ]


Tuning: Standard - Capo 7



                 A                       E
I wished I was smarter, I wished I was stronger.
                F#m                D
I wished I love Jesus, the way my wife does.
                      A                      E
I wished it had been easier, instead of any longer.
                       F#m   
I wished I could have stood
                          D
Where you would have been proud,
                   A
That won't happen now
                   E
That won't happen now.


Chorus:

          D                                 E
There's a whole lot of singing that's never gonna be heard,
     F#m                         D                  A
Disappearing everyday without so much as a word somehow.
D                                 E
Think I broke the wings off that little song bird,
      F#m                    D                       A
She's never gonna fly to the top of the world right now.
          E
Top of the world.

               A                   E
I don't have to answer any of these questions.
            F#m                  D
Don't have no God to teach me no lessons.
                    A                  E
I come home in the evening, sit in my chair.
                              F#m
One night they called me for supper
                D
But I never got up,
              A             E
I stayed right there in my chair.



          D                                 E
There's a whole lot of singing that's never gonna be heard
     F#m                         D                   A
Disappearing everyday without so much as a word somehow.
D                                E
Think I broke the wings off that little song bird,
      F#m                    D                       A
She's never gonna fly to the top of the world right now.



                 A                       E
I wished I'd a known you, wished I'd a shown you,
          F#m                 D
All of the things I was on the inside.
                     A                                E
I'd pretend to be sleeping, when you come in in the morning
                F#m                    D
To whisper good-bye, go to work in the rain.
               A              E
I don't know why, don't know why.


      D                           E
Cause everyone's singing, we just wanna be heard.
    F#m                           D                   A
Disappearing every day without so much as a word somehow.
D                         E    
Wanna grab a hold of that little song bird,
 F#m                       D                       A 
Take her for a ride to the top of the world right now.


F#m  D x4


  F#m     D
Whoa.  Whoa.  


                   F#m
To the top of the world.  
                    D              x4
To the top of the world.  


F#m  D   repeat to end
