This song is very easy to play and is mostly on the A string.
Riff
A-7--6--4--------3--5--2--5-5-5-------
E---------5-4-5-----------------------
Repeat until Crack Part
("I'm not gonna crack....")
A--0-0-3-3--
Repeat that 16x and then go back to the Riff.
After repeating the Riff so many times again
return to the crack part, and end the song after that.
