[Verse 1]
E
Speaking as a guy who's really got it going on
          A       Bsus4           E  A/E  E  A/E  E  A/E
It's only natural      It's only me
E
Take it from a fella who's been round the block so many times
                                      A    Bsus4
He knows the only parking spot that's free,
          E
It's only me...

[Chorus]
A                      E
You can say I've tried everything,
A            E
I save on my wedding ring,
A            Am              E  A/E  E  A/E  E  A/E  E
Who knows me half as well as me?

[Verse 2]
I'm not antisocial, and it's nothing that's reproachful
It's just natural! - It's only me!
I can't think of anybody else I'd rather spend some one on one time with
It's not that hard to see,
It's only me...

[Chorus 2]
I'm the me in monogamy,
I'm not asking a lot of me,
I give me R.E.S.P.E.C.T.

[Bridge]
N.C.        A/C#  E/B  B  E
And if your heart is   broken,
A                        E
You can just do what you do best,
A            E
You can just do what you do,
          A/C#  E/B  B  E
When your heart is   broken,
A                         E
Trust in the one who will love you
A                  E
Never put others above you

[Verse 3]
I thought I was using me to get to you,
But this is true and natural
It's only me
They say you'll never love another 'till you love yourself
Well brother, I'm in love with everyone I see
It's only me...

[Chorus 3]
You can say I've tried everything,
I save on my wedding ring,
Who knows me half as well as me?
I'm the me in monogamy,
I'm not asking a lot of me,
I give me R.E.S.P.E.C.T.

[End on E]
