Spotify Wrapped, a social media hit every year, is a way for Spotify to brag about how much data it has collected on its users.
It's a year-end review of listening habits meant to make surveillance sexy, silly and shareable.
Other companies, including Apple Music, Starbucks, Tesco and Duolingo, have followed their lead with similar data roundups.
These year-in-review trends show businesses have gotten people past objecting to surveillance and got them to celebrate it instead.
While Wrapped content packages data, people are also making up new categories themselves, documenting parts of their lives not captured by apps.
Spotify has also started making daylists, curated playlists released multiple times per day, that hint at something about the user and their data.
Big Tech watching every move has resigned people to the fact, but new year-in-review customs prove people are still excited to see data presented to them.
However, their popularity indicates to some that Wrapped and other year-end reviews are part of the hypersormalisation of the idea of being spied and data mined on.
The Wrapped AI podcast features two voice-bot hosts discussing your listening habits without saying much about the songs.
Wrapped content provides free advertising for companies when it is reshared.
