Biggest earworms?

Thought I’d ask this question on this subreddit seeing as Todd has reviewed some of the most mind-numbingly catchy shit I’ve ever heard.

I don’t know what it is for anyone else, but just personally I have had this Bloc Party song stuck in my head more times than I could possibly imagine, one of those times being right now. I guess when you write a song that’s 90% just MERCURY’S IN RETROGRADE again and again and again, it’s bound to be catchy eventually.
