Why Certain Songs Instantly Transport You Back

One chord and you are seventeen again. Here is why.

A song comes on and suddenly you can smell a summer from years ago. Music is uncannily good at time travel, and the reason is deeply human.

Your brain files strong memories alongside the sounds present at the time. Replay the song and it can drag the entire scene back up with it.

The teenage years are especially sticky. Music you loved while your identity was forming gets bonded to who you were becoming.

That is why a random old track can flood you with feeling in seconds. It is not just a song, it is a key to a room you had almost forgotten.
