Explo

Explo is a self-hosted music discovery tool designed for people running their own music servers. It uses ListenBrainz recommendations to generate personalized playlists (similar in concept to Spotify’s Discover Weekly) and then fetches matching tracks into your library.

Key Features

• Retrieves personalized recommendation playlists from ListenBrainz (Weekly Exploration, Weekly Jams, Daily Jams)
• Downloads recommended tracks from YouTube, Soulseek, or both
• Adds basic metadata (title, artist, album) to YouTube downloads
• Creates playlists directly in supported self-hosted music systems
• Keeps previous playlists for later listening and library continuity

Use Cases

• Automatically refresh a weekly discovery playlist for a Navidrome/Subsonic-style music library
• Fill a Plex/Emby/Jellyfin music collection with recommended tracks based on listening history
• Build an always-updating personal “radio” pipeline using ListenBrainz plus automated downloading

Limitations and Considerations

• Recommendation quality depends on ListenBrainz data and the accuracy of your submitted listening history
• Download sources (YouTube/Soulseek) may vary in availability and metadata quality

Explo is a practical bridge between recommendation engines and self-hosted media libraries, combining automated playlist generation with track acquisition. It’s best suited for users who want hands-off discovery while keeping their music collection under their own control.
