This is a pretty simple song, I have not seen it on here either. I tabbed it out by ear and used some covers
that sounded accurate. 
It sounds all there to me, leave a comment if there are any changes you would make.

       Am               G                Dm            C            Dm 
When I look to see the sun, I can feel positive and negative at once                  
 C              G 
Cuz it Could be a brand new day or the same old one

               C                     G

Bridge:
 Am                 G                Dm                C 
Could there be something else maybe,    
Dm              C                 G 
Not something you see or touch but something That You felt 
Am                    G      Dm         C 
And there Could maybe be the road 
Dm                      C               G 
Underground like sin, it stays in the corners of my soul  

Chorus:
