This is an amazing song with amazing lyrics.  I decided not to have the
number of repetitions per riff since it's pretty obvious when they blend
into each other, and they're different every time.

Those are all of the parts, but the guitar and bass are so close together,
some parts can be played an octave higher, of in Riff 4's case, maybe an
octave lower.
