When you ask me to think of iconic company jingles, the first thing I think of is Meow Mix. I know, horrible and super lame, but it sticks in your head forever! I had a friend in high school that would sing it randomly at least 3 times a week and it was the most annoying thing ever. Here‘s a version of the commercial for you to get annoyed at as well.
Another iconic jingle that comes to mind is Goldfish. “The Snack that Smiles Back, Goldfish,” was like a theme of my childhood. Me and my siblings were all obsessed with them growing up. We still get the big cartons from Costco and go through them in a couple days. Here’s a very annoying version of the jingle that just plays that one iconic line over and over again for the different iterations of the many goldfish commercials.
I hope this has been annoying enough for you and that you spend the rest of your week hating me for getting these jingles stuck in your head.
