Universally Speaking
stonker of a tune, worked out on acoustic, pretty easy to play. Enjoy!

intro D Em7 x 4

D    Em7
i saw your face
       D
Elegant and tired
  Em7
Cut up from the chase
     D
Still I so admired
  Em7
Bloodshot your smile
      D
Delicate and wild
  Em7
Give me she wolf style
    D
Rip right thru me
D       Em7
Silveretta the jets of a lifetime
     D
Go and get her i've got her on my mind
     Em7
Nothing better then feeling is so fine
    D
Simply put I saw your love stream flow


A
Come on baby 'cause cause there's no name for
Am7
Give it up and I got what I came for
G   Bm
Universal-ly speaking
A
Take it back and you make me nervous
Am7
Nothing better then love and service
G   Bm          Am
Universal-ly speaking ah
B7  Em
Win in the long run

I saw your crime
Dying to get high
Two of a kind
Beat all hands tonight

我这看不了视频，按和弦猜测：
Am7是D大调的小属7
在G-Bm-Am-B7-Em的进行中，以Am7为中介转到了e小调。
最后B7-Em的进行是结束在e小调上。
