Excerpt from this article:
Streaming music service Spotify has identified 42 as the age when many of its users rediscover the joys of current pop music, as part of research into how their tastes mature over time.
“We’re starting to listen to ‘our’ music, not ‘the’ music. Music taste reaches maturity at age 35. Around age 42, music taste briefly curves back to the popular charts — a musical midlife crisis and attempt to harken back to our youth, perhaps?”
The findings come from a study conducted by Ajay Kalia, who oversees Spotify’s “taste profiles” product, which tries to understand people’s tastes based on their listening habits.
