Spotify

Music streaming, and the training playlist people build inside it

Streams music and podcasts on a free tier with ads or a paid one without. What puts it in training routines is the playlist: a fixed running order for the warm-up, for the hard intervals, for the walk home. The year-end Wrapped summary turns twelve months of listening into something people pass around.

    At the end of 2025 she gave the newsletter over to two of her own things instead of the usual science: a solo gym workout she called a rare share, and the highlights of her Spotify Wrapped.
