What's the Soundtrack of Your Week?
Nobody listens the way their profile suggests. There is the music you would put on a list for other people, and then there is whatever has genuinely been in your ears while you walked to the shop and stared at a spreadsheet.
This is about the second kind. Seven questions on volume, repetition and what you reach for when the week gets long, and a soundtrack shape at the end. Afterwards there is a proper read on why the songs you loved at fifteen refuse to loosen their grip, and what repetition quietly does to liking.

Why the music from your teens will not loosen its grip
Ask people to recall events from across their lives and the results come out lopsided. Memories cluster around roughly ages ten to thirty, a pattern David Rubin and colleagues documented and labelled the reminiscence bump, and for music the peak sits earlier still, somewhere in the teens. The usual explanations are that identity is being assembled at that age, that a lot of things are happening for the first time, and that encoding is unusually sharp.
Carol Krumhansl and Justin Zupnick added a wrinkle in 2013. Playing chart hits from decades before their undergraduate participants were born, they found extra peaks of liking and personal association around the music of the students' parents and even grandparents, which they named cascading reminiscence bumps. Taste is inherited across a kitchen as well as assembled in a bedroom.
The taste freeze, measured on a very large sample
In 2015 Ajay Kalia, then working at Spotify, published an analysis of listening data suggesting that engagement with current chart music falls steadily from the early twenties, drops sharply around thirty-three, and that becoming a parent shifted listening habits by several years' worth of taste. Worth being clear about what that is: a company blog post built on enormous proprietary data rather than a peer-reviewed study anyone outside can check.
Academic work points the same way more cautiously, generally finding that the intensity of new listening drops after early adulthood while attachment to what was learned then holds firm.
Repetition is doing more of the work than you think
Robert Zajonc's mere exposure experiments, published in 1968, showed that simply encountering something repeatedly nudges people towards liking it, with no memory of the encounters required. Daniel Berlyne supplied the shape: liking climbs with familiarity and then falls once a piece becomes wholly predictable, an inverted curve that accounts for both the grower album and the song you have finally killed.
Elizabeth Margulis went further in her 2014 book On Repeat. She took pieces by composers famous for avoiding repetition, spliced segments and looped them, then played the doctored versions to listeners, who rated them more enjoyable and more likely to have been written by a human. Diana Deutsch's speech-to-song illusion is odder still: an ordinary spoken phrase, repeated unchanged, gradually starts to sound sung.
None of which a seven-question quiz can measure. It offers a shape to argue with, and a reason to notice what has genuinely been playing all week.
