Do you remember which soap? If not, any of the lyrics whatsoever? Especially the hook, or chorus if you will. Just one line of that and it will come up if you google it. Believe me I know what you are talking about. I can't watch a program without reading the credits. It drives me crazy when I can't remember an actors name, who did a song, etc. Thanks to the internet it's much easier. I spent three days once years ago before the internet trying to think of Peter Lorre's name! LOL
Anything you can remember will help, program, characters involved in the story line. Anything.
