It's First Pitch is B Natural

I'm going to sing you a happy song when I remember its words,
  The verses start with a consonance to outline the song's happy terms,
One such phrase was "loving you," then something about "best friends,"
  But that part is long before the chorus; that isn't how it ends.

I'm going to sing you a happy song if my feet can remember the rhythm,
  When the band kicks in and the song picks up, I can feel my heart beat with 'em.
And the chorus rings as the singer sings out an anthem of lies and truths,
  I can feel in the Bridge that he needs her to be his,
    that he wants her to be close and to show her what trust is.

I'm going to sing you a happy song, though the chords are as boring as hell,
  But they perfectly showcase the melody's truth as my love sounds aloud like a bell,
I could whisper in time with an elegant rhyme but, my love, it just won't be the same,
  'cause this song's only lyric--and I alone hear it--is simply the sound of your name.
