I fiddled around with chords so it may not be 100% correct. The chords run 
throughout the whole song. Enjoy! =)

PS: This is my first tab i've made.

Standard Tuning
G/Dsus4/Em7/Cadd9

G     (320033)
Dsus4 (xx0233)
Em7   (022033)
Cadd9 (x32033)

    G
The rain falls on my windows
        Dsus4
And the coldness runs through my soul
         Em7
When the rain falls, oh when the rain falls
        Cadd9
I don't want to be alone

     G                          Dsus4
I wish that I could Photoshop on
Our bad memories
          Em7
Because the flashbacks, oh the flashbacks
      Cadd9
Won't leave me alone

       G
If you come back to me
      Dsus4
I'll be all that you need
      Em7
Baby, come back to me
      Cadd9                              G
Let me make up for what happened in the past


Baby come back to me
   Dsus4
Come back
I'll be everything you need
    Em7
Come back
Baby come back to me
   Cadd9
Come back  
                            G
Boy, you're one in a million

Baby come back to me
   Dsus4
Come back
I'll be everything you need
    Em7
Come back
Baby come back to me
    Cadd9
Come back
Boy, you're one in a million
