It's a well known phenomenon.
Oorworm, Ohrwurm, ear worm...
The Germans use the word Ohrwurm to denote these cognitively infectious musical agents. Whenever somebody complains to you that he just can't keep the latest (pop) tune from running through his head, tell him he can dispel it by calling it by name and by thinking about the original German meaning, which captures some of the mnemonicalli parasitical connotations of the word, for Ohrwurm literally means "ear worm" and is also used to refer to a kind of worm that can crawl into the ear.

Abba songs , children's ditties, and for the Dutch & Belgians among us the songs by K3 - three would-be-nice&childfriendly Flemish singers of Studio 100 fame ( they are huge in the Low countries) = all possible ear worms.. I really hate them for their phony friendliness . Do not ,I repeat DO NOT listen to their songs.
