Had to post a simpler tab to play along with Glee's version of Defying Gravity, 
some of the other tabs out there are misleading.  I'll make it as simple as pie.  
I like to add9 to the G's but either way's fine.  The only chord I'm unsure of is 
the Am before the 2nd chorus but it sounds really good.

Capo 6.

[Verse 1]

             
Something has 


changed within

 me
            
Something is n

ot the same
             
I'm through wi

             
th playing by 

    
the rules
          
Of someone els

e's game
            
Too late for s

econd-guessing
             
Too late to go

         
 back to sleep
            
It's time to t

rust my instin

cts
             
Close my eyes 

    
and leap

[Chorus]

             
It's time to t

And you won't 

        
bring me down

[Verse 2]

             
I'm through ac


cepting limits
            
'Cause someone

  
 says they're 

so
             
Some things I 


cannot change
            
But 'till I tr

Too long I've 


been afraid of
             
Losing love I

Well, if that'

It comes at mu

[Chorus]
           
I'd sooner buy
