Every Noise at Once

Every Noise at Once is a music discovery website created by former Spotify employee Glenn McDonald. It operates as a directory of musical genres, artists, and tracks listed by Spotify, in a scatter plot word map style. Since December 2023, McDonald has no longer been able to update the site with new data after he was laid off from Spotify.

In 2019, McDonald's metadata contributions to Spotify's algorithm, which drew from Every Noise at Once, led to the creation of the influential "hyperpop" Spotify playlist. Led by senior editor Lizzy Szabo, the playlist became instrumental in the wider popularization of the movement.
