Stronger - Britney Spears
It took a couple of days to get right, but here's what I come up with. 
I'm not sure about the bit before the last set of choruses ('here I go, on my own...')
But otherwise it's pretty much the same thing. Any questions or improvements, seriously,
(Sounds best with barre chords)
Intro:- G G..(ooh...hey-yeah) G G G
Verse:-
A     A    A       (deaden strings)
Hush, just stop...
                        F        E
There's nothing you can do or say (ba-by)
     A                                    F         E
I've had enough, I'm not your property as from today (ba-by)
C#m        G#                 Gm
You might think that I won't make it, 
      A#
On my own, but now I'm...
Chorus 1:-
C             A      C                         Bb G#
Stronger than yes-terday, now it's nothing but my way
   C      Bb         Bm      G#    Gm
My lon-li-ness ain't killing me no more
C#m Bbm    Cm
I - I -'m  stronger...
Verse 2:-
       
                         F         E
Than I ever thought that I could be (ba-by)
  A                                       F       F#m
I used to go with the flow, didn't really care 'bo_ut me
Bm        F#                 Fm
You might think that I can't take it
       F#
You're wrong, 'cause now I'm...
CHORUS
Then the bit where she's in the car:
Cm
Here I go, on my own now,
        Bbm
I don't need nobody not any body,
Cm             B  Bb   G         A  Bb  Bm
Here I go............alright............Here I go...
Chorus 2:- (Dm is at 10th fret and Em at 12th)
Dm              Cm     Dm                        Em Dm
  Stronger than yester-day, now it's nothing but my way
   Cm     Bb         Bm      A     G#
My lon-li-ness ain't killing me no more,
C#m Bbm    Cm
I - I -'m  stronger~~~~
CHORUS 1 TO THE END
As I say, it is nowhere near perfect! But, it's a good go! The bit where
she is in the car is probably the confusing bit. If you follow the harmony 
in the background on the song, you'll see how I picked it up! Good Luck
