it is pretty simple. though i am still having trouble figuring out the pre-chorus.
i submitted a bass tab for this before but i realised two days after that it was wrong.

tunning is standard.

G------------------------------------
D------------------------------------
A---333------------------------------
E-------1----------------------------

Repeat that throughout the verses.

PRE-CHORUS "did you notice....."
G-----------------------------------
D-----------------------------------
A-----------3--3335-3---------------
E-001--03---------------------------

CHORUS
G------------------------------------
D------------------------------------
A---333----333----222----222--------- 
E-------1------1------0------0-------

Just repeat that throughout the chorus.

BRIDGE
G------------------------------------
D------------------------------------
A-1-------3-------5------------------
E-------------------------1----------

Then repeat the chrous after the bridge, then the verse. and then end on
G---------
D---------
A--333----  Let Ring.
E------1--
