Chords:

C  X32010
Am X02210
Em 022000
G  320033 OR 320003
F  133211

Note: On the studio recording she plays F in the verse, live it's Em. Either 
sounds fine, just keep it the same throughout.

Strumming tends to start at the beginning of the second verse.

The riff can be played with strumming by switching between C and Csus4 at the same 
rhythm as in the intro.

Pretty much sure this is right; if you want to add ornamentation try switching 
between Am and Asus2
