I had the same idea a little while back and ended up creating playlists by year going back to the mid 90s. It’s a great way to deep dive and create “keys” to memories.
However, there is one major flaw. I’ve found that treating music as a key to unlock memory from certain periods means I tend not to revisit that same music casually because I know that each time I listen to music it gets re-encoded to current events in time.
I can’t remember where I read that (some study from ages ago) but basically if there was a song you listened to a lot as a kid and then you hear it again it will remind you of that time in your childhood, but if you keep listening to it then the song also gets attached to current memory and in 20 years when you hear it again you will have a mix of childhood and adult memories flooding back - or some diluted memory.
It might not work that way for everyone but I’ve found it to be true at least in my own personal experience.
That's interesting, I have never had this re-encode thing. No matter what, "Backstreet Boys" will always stick with my school student period.
I think the main reason is it's really hard to re-listen to a piece to the same intensity as when you first heard it. I used to put Backstreet Boys on repeat for a whole week at times, and also sat through some of their sub-par pieces. Now I only listen to their best-of-playlist, in about an hour, maybe once a year.
