He plays the Cmaj7 like this (x35500, sort of like a power chord),
but you can play it even easier (x32000), sounds close enough.
Dsus2 is just a regular open D chord with the top string open (xx0230).
Similarly G6 is a G with the top string open (320000).
In the end solo he plays the chords by moving the Cmaj7 power chord shape up the neck.
So Dsus2add13 looks like this (x57700), E5 is (x79900) and G6 is (x 10 12 12 0 0).
The intro and the majority of the song just alternates between Cmaj7 and Dsus2.
Cmaj7 Dsus2
On tour
Lord of the flies
Aw, hey, who cares?
What's a guitar?
Watch out for this one
He'll stab you in the back for fun
I'm just playin'
I know you, man,
Most of the time
Watch out for this one
He'll pump you full o' lead for turnin' your head wrong
I would know
I see through everyone, even my own self now

Am G
I wanna write my whole life down
Cmaj7 Dsus2
Burn it there to the ground
Am G6
I wanna sing at the top of my lungs
Cmaj7 Dsus2
For fun, screaming annoyingly
'Cause that's just me
Cmaj7 Dsus2
Being me, being free
Watch out for this one
He'll pump you full o' lead for turnin' your head wrong
I would know
'Cause I can see through him and them
On tour
Lord of the flies
I'm just playin'
I got it made
Most of the time
Am G6
I wanna beat on a drum so hard
Cmaj7
'Til it beeds blood
Dsus2
Pull out the heart
Am
'Til it don't start again
G6 Cmaj
Solo
Am Cmaj7
