Play that riff for pretty much everything but:
-verse
-last line of the chorus
and
-the bridge

theres also a part where its just drums

I havent figured out how the guitar part goes when it goes "I dont understand..."
I'll post it when I figure it out so keep checking on it

*This is one of my favorite songs
my friend got me hooked on it
its an easy song so enjoy!
