Hey! I've learnt this from ear so sorry if some parts are a little bit wrong, and sorry 
if the lyrics are wrong, he hasn't released the official song yet so this isn't the full 
version :)

Standard tuning

Am
I've been trying to find the right words
G        D                            Am
But they always seem to hit the page wrong
                             G
You see I tend to fight words
   D                                   Am
I breathe 'em into life, and they're gone
                                   G
I need some louder speaking actions
     D                           Am
They do what letters could never do
                    G
You see, you are my addiction
       D
I need more than words to show you


(chorus)
      Am C      G  D    Am  C
So listen to me, listen
G             D
Listen to my heartbeat


Am                                 G
I'd like to think you understand me
      D                       Am
But I never really like to assume
                          G
So you never have to ask me
       D                          Am
I'ma let my actions tell you the tru-hu-huth
     C
For you-hu-hu-hu
G                             D
There is nothing I wouldn't go through-hu-hu-hu
Am                   C
And if you need some proo-hu-hu-oof
G                         D
You can find it in what I do-hu-hu-hu

              Am                         C
(listen to me baby) And I could tell you everyday
G                    D
Just how much I want you
  Am               C
I-I-I-I I've never been good with words
      G                            D
But I went and wrote this song for you
