A
As you move out of your teens and into your 20s and 30s, your musical tastes start to solidify and you likely quit keeping up with popular music. Now, research has found the average age at which your music library is unlikely to change: 33.
The study’s author reached this conclusion by analyzing data on US Spotify users and comparing it to artist popularity data from music intelligence company The Echo Nest.
To determine the age at which we stop seeking out new tunes, the author gathered selfreported age data from Spotify and looked at users’ “Taste Profiles”， which tracks how many times listeners have streamed individual artists. These artists were then matched to their popularity rank on The Echo Nest.
The average teen listens almost only to music among the Billboard, the 200 highestranking albums in the country, but this music represents a smaller part of their streaming as they age. In their teens, they listen to a lot of the same music, over and over again. Frank T. McAndrew, a professor of psychology at Knox College, explains that’s the “mere exposure effect” at work, and it basically means, the more we’re exposed to something, the more we like it.
There are many reasons why a person may stop streaming the current top musical hits, and the author looked into one by identifying Spotify listeners with large amounts of children’s music and nursery rhymes in their libraries. In other words, when users may have become parents.
But the study concludes with some good news for parents: “If you’re getting older and can’t find yourself staying as relevant as you used to, have no fear — just wait for your kids to become teenagers, and you’ll get exposed to all the popular music of the day once again！”
