Note regarding Riff 2:
The timing here sounds a little odd, as the first time 2a is played, it is
used as a fill. It is still played 8 times, but while you subconsciously
count in your head, it will sound like 7 because you will most likely ignore
the time it is used as a fill. 2b is merely the end to that passage of the
song.
