When you confuse two songs that have the same title and that came out near the same time? For example:
Duran Duran’s “Notorious” (1986):
Loverboy’s “Notorious” (1987):
It was the video for “Notorious” that I had in mind for some reason. Sadly, I didn’t look 80s cool until the early 90s, and that made for some lonely times and few dates at college.
Another similar circumstance: Robbie Nevil’s “C’est La Vie” (1986):
And David Lee Roth’s “That’s Life” (also 1986 — sorry, no video). Both songs charted at the same time, but fortunately one is titled in French to alleviate the confusion.
