verse part c/pre-chorus
the only difference between the verse and the pre chorus is that the verse is played with
quick, short chords, and the pre chorus is played smoothly. (strumming is a little off, you 
can figure it out) the timing here is a bit quirky,so add muted notes as fills whenever needed.
