Why Songs Get Stuck In Your Head

We've all had those songs that lodge themselves into our brains
and refuse to get out. Why are we so prone to this happening, and
what certain types of songs are more commonly sticky? We'll
discuss a number of factors, plus the science behind what's
happening in our brain when a song gets stuck, and how repetition
in music feeds into a basic human need for comfort and safety.
We'll also talk about supposed cures for earworms - and one thing
that is scientifically proven to get rid of them.
