How the ranking works: most of each song’s calm score comes from its Spotify-style audio features: low energy, high acousticness, low danceability, a slower tempo and a lower volume all count as calmer. The rest comes from our own listening measurements: how sharply the notes start, how often the volume jumps, how much the level moves and how bright the tone is. Songs with vocals and the Halloween records are left out. More in the guide.
