Em
Love is your weapon of choice
Em
Love, Love, Love
Em
Love, Love, Love
Em
It's your weapon of choice

Am
You're invading my heart
      D                     Em
Every time that I hear your voice
        Am
And I'm screaming out "Surrender"
        D                      Em
But you can't hear me as you rejoice

         Am                              D
You're a General shouting orders to your army
    Em
The command you are giving is to harm me
             Am
Harm me with love 
        B                      G
Because that is your weapon of choice

(G)                           F#/D
And what was that about last night?
                  Em
Why do we have to fight?
                                F#/D
You conquered my body with your kissing
                       G
Your caresses are your ammunition

(G)                               F#/D
Every time you walk in through my door
                          Em
You're extending this war metaphor
                                  F#/D
You leave me wounded lying on the floor
                             G
I think I've seen this floor before

Em
Love that's your weapon of choice
Love, Love, Love
Love, Love, Love
Love that's your weapon of choice

          Am                     D
There's a battleship loaded with emotions
                      Em
Crashing on a samurai ocean
         Am                    D
And I'm afraid it's just as I feared
                         Em
This ocean is made of my tears

B
Love is the weapon
B
Love is the weapon with which you choose to threaten
B                      Em
Love is your weapon of choice
