Why do so many people stop listening to new music after age 30? Let’s ask science!

Let’s ask science! Why do so many people stop listening to new music after age 30?
After 24, it’s all downhill. By age 30, it’s often just easier to default to the favourite music of your youth. Family. Tastes eventually “mature” until we reach our early 30s. (Via Silence Alert)
  ‘Course, none of these applies to you, right? The same songs over and over again work just fine for them. Deezer commissioned a survey of 1,000 people in the UK about their music preferences. We also have lots of time and energy to devote to sourcing out music–especially new music–that touches us. People report difficulties keeping up with what’s new and cool. Music in our teen years is dominated by current music, the stuff that’s new and cool. Instead, nostalgia takes over and the music of our youth becomes dominant. They discovered that the peak age for music discovery is 24. Mortgages. Need more? That means 53% just can’t be arsed anymore. Songs from your teens will be popular again among people of your same age a decade later. All of us go through a coming-of-age period when it comes to music, beginning roughly when we enter grade 9 and continuing through until our early 20s. But by the time our mid-20s approach, life starts to get in the way. 25% reported being open to new music
19% complain that there’s too much music out there and they’re overwhelmed by the choice
16% say having a job is getting in the way
11% say they’re too busy with children and family
About half the people (47%) said they wished they had more time to devote to music. The amount of time and energy left over to devote to music begins to diminish. About 64% said that they listened to five new artists every month. Right? Deezer, the France-based streaming service, is also interested because this sort of thing directly affects their business. Science is most interested in this behaviour. 60% say that they’re in a rut musically. Jobs. This is based on the metric of listening to 10 or more new tracks a week. Another survey of music preferences using data from Spotify offered up these facts. By 33, a sizeable number of people had stopped listening to new music entirely. As we figure out who we are as people, we use music to understand ourselves and then to project that identity to the world.
