"I've Got the World on a String" was one of the Frank Sinatra songs Vic Fontaine sang for Nog during Nog's bout of depression following AR-558. (DS9: "It's Only a Paper Moon")
Lyrics
I’ve got the world on a string
I’m sitting on a rainbow
Got the string around my finger
What a world, what a life - I’m in love
I’ve got a song that I sing
I can make the rain go
Any time I move my finger
Lucky me, can’t you see - I’m in love
Life’s a wonderful thing
As long as I hold the string
I’d be a silly so-and-so
If I should ever let her go
