I can't believe no one mentioned "London Bridge is falling down falling down falling down London bridge is falling down my fair lady."
Here's what seems to have happened throughout a lot of DS. You had one song or one sequence that you heard over and over for a period of time then they moved on to something else and it was a new something or other that you heard over and over ad nauseum.
1) London Bridge, early Barnabas storyline
2) Josette's theme, early Barnabas storyline
2) "A seance has been held in the great house of Collinwood... 1795 storyline. And note how one day they'd say girl and the next woman. They never could make up their minds whether Vicki was a girl or a woman. Why couldn't they say young woman?
3) "Julia, when you do the experiment again..." Adam storyline
4) Quentin's theme, ghost of Quentin storyline, 1897 storyline
5) Angelique's theme, parallel time storyline. I never got tired of this one though, I loved it.
6) The carousel music 1995 and summer of '70 storyline. I don't think we heard it once we moved into 1840.
I don't remember others than these. But with each one you'd hear it during that storyline only, after that never again.
