Before I begin the tab, I would like to say this is the first tab 
that I've ever created. It's a pretty easy song, and I haven't 
been able to find this tab on this internet, so that was suprising 
to me. I should note that I figured this all out by ear, so if anything 
seems off that's why.. But anyways, onto the tab:

Verse — repeat a large number of times
G|——————————————————————————|
D|——————————————————————————|
A|——7—7———7—7———7—7—5—7—7———|
E|——————7—————7—————————————| 

You can also just repeat this
G|——————————————|
D|——————————————|
A|——7—7———7—7———|
E|——————7—————7—|

Chorus — repeat four times
G|————————————————————————————————————————————|
D|————————————————————————————————————————————|
A|——7—7——5—7——7—7—5—5—7—5——5—5—4—5——5—5—4—2—0—|
E|————————————————————————————————————————————|

G|————————————————————|
D|————————————————————|
A|——4—4—2—0—2—0———0———|
E|——————————————4———0—|
After this part there are different end parts throughout the 
song and I'm pretty sure I figured most of them out. So you play 
the Chorus, then end with one of the parts, and then after playing 
a part play the Chorus again (except after the last (fourth) 
time through when you have to go back to the Verse):

Part 1:
G|——————————————————————————|
D|——————————————————————————|
A|——2—2222—22—0———00————————|
E|——————————————4———————————| 

Part 2:
G|——————————————————————————|
D|——————————————————————————|
A|——2—2222—22—4—2—0—2—22————|
E|——————————————————————————|

Part 3:
G|————————————————————————————|
D|————————————————————————————|
A|——2—22222/14—14141414141414—|
E|————————————————————————————|

Afterwards, the song just goes back and forth between the two 
parts. So here's the times that the different parts are played:
Verse 0:00 to 3:57
Chorus 3:58 to 4:57
Verse 4:58 to 7:41
Chorus 7:42 to 8:40 
Verse 8:41 to 10:09
Chorus 10:09 to end

That's all there is to it, I hope you enjoyed my first Bass tab :)
