THE FOREVER JUKEBOX

What the what?

The Forever Jukebox is an open-source modernization of Paul Lamere's Infinite Jukebox and Autocanonizer — rebuilt from the ground up and launched on January 1, 2026 by Creighton Linza. It generates a forever-evolving version of any song.

How does it work?

The app uses the Spotify Web API for track search/metadata and YouTube as the audio source. The audio is processed by the Forever Jukebox Analysis Engine, which approximates Spotify’s legacy Echo Nest analysis (now deprecated) by extracting beats, segments, and related features. Those features drive beat-synchronous playback in the frontend. On each beat, the player may jump to a different, sonically similar point in the track based on timbre, loudness, segment duration, and beat position. The visualizations map these potential jump paths for every beat.

The full source code is available in the forever-jukebox repository.

How can I tune the Jukebox?

• Click the Tune button to open the tuning panel.
• Lower the threshold for higher audio continuity; raise it for more branches.
• Adjust branch probability min/max and ramp speed to shape how often jumps happen.
• Use the checkboxes to allow or restrict certain branch types.
• Click a branch in the visualization, then press Delete to remove it.

How do Favorites work?

• Favorites are saved/unsaved by clicking the star icon on a song. They are stored locally in your browser and can optionally be synced across devices using a sync code obtained from the Favorites sync menu.
• When you favorite a song, its tuning and deleted branches are saved too, so future loads restore your chosen parameters.
• Use Reset in the Tune panel to restore default tuning and deleted branches (must be re-favorited to save changes).

Installable Offline App

For local/offline analysis and playback, open the Forever Jukebox Offline app and install it from your browser.
