Every click autosaves in this browser. Export backups regularly, especially before switching computers or clearing browser data.

Spotify setup & connection

Create a Spotify developer app, then enter its Client ID below. Add this page's exact URL as a Redirect URI in your Spotify app settings. Use a local HTTP server at http://127.0.0.1:8765/ (not localhost or file://). Premium and API access are required for playback commands. This app never transfers playback to another device.

Keyboard shortcuts & help

Enter: save and next · Arrow Left/Right: navigate · Space: play/pause (when not typing). Songs are sorted A–Z by title, ignoring leading A, An, and The. Any number of playlists may be selected. Skipping marks a song for later. “No playlists fit” marks it reviewed with zero assignments. Playback begins automatically when navigating if connected.
