One of my favourite songs and its also pretty easy to play. Only 5 chords.
STANDARD TUNING AND NO CAPO 

*Single strum

Intro: F#m, E, D, Bm x2 

F#m*                        E*
Nothing is perfect but your imperfections are quaint
D*                                Bm*
And your love is worth it and for that I will wait
F#m*                         E*
And though you hate me, when you have a turn
D*                        Bm*
I drive you crazy but you always return


F#m
If I fall short
E
If I break rank
D
It's a bloodsport
Bm
But I understand
F#m
I am all yours
E
I am a man
D
I'm on all fours
Bm
Willingly down


F#m                        A         D        Bm
Loving you is a bloodsport    
F#m                        A         D        Bm
Fighting in a love war


F#m* -pause-


F#m                   E
Although you love me, sometimes we meet
D                       Bm
Things can get ugly but we're still a team
F#m                 E
We are an army, the brakes are within
D                                  Bm
But that's why we're stronger, and that's how we'll win


F#m
If I fall short
E
If I break rank
D
It's a bloodsport
Bm
But I understand
F#m
I am all yours
E
I am a man
D
I'm on all fours
Bm
Willingly down


F#m                        A         D        Bm
Loving you is a bloodsport    
F#m                        A         D        Bm
Fighting in a love war

F#m                            A
It's not what I'm in love for, I'm sure
D
But I don't know if you can't help it
Bm
Maybe, I'm just being selfish

F#m                        A         D        Bm
Loving you is a bloodsport


F#m*                   E*
I've got your back and though it's stacked against us
D*                       Bm*
I've got your hand, it's us against consensus
F#m*                E
And I will burn the people who hurt you the most and I will not learn
D
'Cause I am too young and too dumb to consider the terms
Bm
I'm breaking the law and I'll curse the day that they return
F#m
With a smile on my face as their heads hit the floor
E                                                                           D
And it's done, now it's curtains, the blood lost, it's the cost, it fucking hurts
                                           Bm
But it's working and even if you ask me to stop it's too late
                                  F#m
Because I've already decided that faith is not a distaste, it's pure hate
                       E
And it pulsates and it works its way around my brain
                    D                                                        Bm
And anyway, what I'm tryna say is I'll protect you till the day I'll meet my maker
                                                       F#m
So don't fight me now 'cause you might need me later


F#m*                       A*        D*       Bm*
Loving you is a bloodsport    
F#m*                       A*        D*       Bm*
Fighting in a love war

F#m                            A
It's not what I'm in love for, I'm sure
D
But I don't know if you can't help it
Bm
Maybe, I'm just being selfish


F#m                        A         D        Bm
Loving you is a bloodsport
