Streets - Omg chords

Artist: The Streets
Song: OMG
Album: Computers & Blues

The song follows the same chord progression throughout for most of the song:

G - Em - C - G
[ Tab from: http://www.guitaretab.com/s/streets/262887.html ]
I would recommend playing it with bar chords.

The three notes played in the intro and chorus is: 

high e: 9-----12------14 x3 ends on: 9-----12------7

I know this isn't very difficult, but i still hope i managed to help someone.

Peace out
