"Stay"
Zedd, Alessia Cara

[Verse 1]
C               Em               D
Waiting for the time to pass you by
C                 Em                      D
Hope the winds of change will change your mind
C              Em               D
I could give a thousand reasons why
          C    Em             D
And I know you, and you've got to

[Pre-Chorus 1]
C                        Em
Make it on your own, but we don't have to grow up
D                   G
We can stay forever young
C                  Em
Living on my sofa, drinking rum and cola
D                     G
Underneath the rising sun
C              Em               D   G
I could give a thousand reasons why
           C    Em          D
But you're going, and you know that

[Chorus]
G                     C      Em
All you have to do is stay a minute
     D          G
Just take your time
    C        Em           D
The clock is ticking, so stay
G                  C      Em
All you have to is wait a second
     D        G
Your hands on mine
    C        Em          D
The clock is ticking, so stay

[Post-Chorus]
C Em D G
*Beat*
C Em D G
       All you have to do is
C Em D G
*beat*
C Em D G
       All you have to do is stay

[Verse 2]
C                Em        D
Won't admit what I already know
     C              Em              D
I've never been the best at letting go
C             Em               D
I don't wanna spend the night alone
          C     Em      D
Guess I need you, and I need to

[Pre-Chorus 2]
C                      Em
Make it on my own, but I don't wanna grow up
D                   G
We can stay forever young
C                  Em
Living on my sofa, drinking rum and cola
D                     G
Underneath the rising sun
C              Em              D     G
I could give a million reasons why
           C    Em          D
But you're going, and you know that

[Chorus]
G                     C      Em
All you have to do is stay a minute
     D          G
Just take your time
    C        Em           D
The clock is ticking, so stay
G                  C      Em
All you have to is wait a second
     D        G
Your hands on mine
    C        Em          D
The clock is ticking, so stay

[Post-Chorus]
C Em D G
*beat*
C Em D G
       All you have to do is
C Em D G
*beat*
C Em D G
       All you have to do is stay
