Gorillaz - Stop The Dams chords

I cant really tell when the chord changes but yeah. Im just giving you reference 
points on when to change with the words, 
because the chords sound right wherever you play them but anywho goodluck.
One more thing, you have to keep repeating the chords in this order throughout the 
entire song to the beat.

(C,E,F,Em)
