G
Oh the awful title belies the quality
D                Am
Of this unusual comedy
C                  G
It's the same for you and me
G
And the days and nights you remembered me
D
The walls I never seen
Am
Come to me
C                  G
It's an awful tragedy

[Chorus]

Am
Fifty million reasons
C                    G
Loving in the seasons
Am
Fifty million lovers
C                      G
Sitting at the doubles
Am
Fifty million reasons
C                     G
Loving in the seasons
G                          Am
When you cry it pulls me through

[Verse 2]

G
And you know the times we crossed the street
D                              Am
We'd rather laugh than greet. Honestly
C                     G
it's a forgone comedy
G
And you know the walls we tried and made
D                             Am
You know it's never changed. Honestly,
C                       G
it's a long-lost comedy

[Chorus]

Am
Fifty million reasons
C                      G
Loving in the seasons
Am
Fifty million lovers
C                      G
Sitting at the doubles
Am
Fifty million reasons
C                     G
Loving in the seasons
G                            Em Am
When you cry it pulls me through

The main lead riff goes a bit like this. This is the bare bones and is elaborated on at 
other points in the song.

Verse 3: (Same Chords as before)

Oh the awful title belies the quality
Of this unusual comedy
It's the same for you and me
And the days and nights you remembered me
The walls I never seen
Honestly, it's a long lost comedy

Chorus:  (Same chords as before)

Fifty million reasons
Loving in the seasons
Fifty million lovers
Sitting at the doubles
Fifty million reasons
Loving in the seasons
When you cry it pulls me through
