Randy, I totally sympathize.
Bruce and I constantly get earworms, and quite often not as pleasant the ones you are experiencing. We sometimes get stupid radio ads stuck which is really annoying. I love Gino vanelli. I was interested to hear that bit of trivia about him.I also love Elo. Don't mind them as an earworm. Starship, not so much.
I heard that one way to get rid of one is to play a different song as a method to drown out the first. This never works for me. LOL
The hiccups thing is a pain. I get them all the time.
