Capo on 4th

(Verse 1)
E                          C#m
For the way you changed my plans
E                          C#m
For being the perfect distraction
        A                       
For the way you took the idea that I have
   Am
Of everything that I wanted to have
    A                                 B
And made me see there was something missing (oh yeah)
E                          C#m
For the ending of my first begin
(ooh yeah yeah)(ooh yeah yeah)
E                               C#m
And for the rare and unexpected friend
(ooh yeah yeah)(ooh yeah yeah)
        A
For the way you're something that I never choose
    Am
But at the same time something I don't wanna lose
A                                B
And never wanna be without ever again (oh oh)

(Chorus)
           E                         C#m
You're the best thing I never knew I needed
   A                  Am    
So when you were here I had no idea
           E                         C#m
You're the best thing I never knew I needed
   A                 Am
So now it's so clear I need you here always

(Verse 2)
E                    C#m
My accidental happily (ever after) (oh oh oh)
E                                     C#m
The way you slime and how you comfort me (with your laughter)
       A
I must admit you were not a part of my book
    Am
But now if you open it up and take a look
A                                          B
You're the beginning and the end of every chapter (oh oh)

(Chorus)
           E                         C#m
You're the best thing I never knew I needed (oh)
   A                  Am    
So when you were here I had no idea
           E                         C#m
You're the best thing I never knew I needed (that I needed)
   A                 Am
So now it's so clear I need you here always

(Bridge)
D     A                E
 Who'd knew that I'd be here (who'd knew that I'd be here oh oh)
D     A       E
 So unexpectedly (so unexpectedly oh oh)
D     A     B  C#m
 Undeniably happier (hey)
          A                                  B
Said with you right here, right here next to me (oh)

Girl you're the..

(Final Chorus)
           E                         C#m
You're the best thing I never knew I needed (said I needed oh oh)
   A                  Am    
So when you were here I had no idea
           E                         C#m
You're the best thing I never knew I needed
   A                 Am
So now it's so clear I need you here always

Baby baby
A                 Am
Now it's so clear I need you here always
