This point resonates with me. I suspect, for most adults, the number of times you’ve sat and really, really listened to music — let alone, the same thing over and over — is much rarer than when you were a teenager/early twenties.

For this reason, though, perhaps this phenomenon (of mostly loving the music you grew up with) will be less true of young people today. Yes, they’re still more focused on music than adults, but they’re neither as focused even when they’re listening (because, internet) nor is their music focus as concentrated (because they easily have access to so much more selection).
