Two parts to this topic:
What music have you grown out of? (This is music you used to love but that you now find it very hard to enjoy)
What, if anything, caused/spurred the separation?
What music has remained resonant throughout the years? (This is music that still speaks to you like it did when you first listened to it, years or even decades earlier).
What do you think gives it such staying power?
"Music" can refer to specific songs, albums, artists, labels, genres, etc. -- whatever best fits the questions and your musical preferences.
