Why do some songs pop up in our heads randomly?
This morning while eating breakfast a song that I didn't listen to for few months came up in my head for absolutely no reason and that made me wonder why songs or memories reappear randomly, without
Not a professional in that matter, but recently heard about a similar experience. My explanation is that you heard this song in a similar ambient environment. Let’s say a month ago you overslept and decided not to hurry at school/work. Mixed your playlist and started to eat muesli with milk and at the same time, you heard your neighbors talking outside. Your neurons recorded all that without you knowing. The month passed, you overslept again, you are not in the hurry, eating your muesli and neighbors talking outside. Something missing??? Oh yeah "su-summer summertime, summer time sadness"
