The owner reports its position every ten seconds, and the server publishes a snapshot to every device on anything that touches the session. The owner was writing those snapshots back into its own store, so each one dragged playback back to its last report. Reloading another tab did it too, since registering a device publishes a snapshot: the phone jumped back to whatever position was on record, which right after a track change is zero, and the song started over. A device that already owns the session now ignores incoming snapshots and stays the authority on its own position. Snapshots still apply when ownership moves to or away from this device, which is what that branch was written for. Moving audio between devices also flushes the real position first, rather than handing over a ten-second-old one. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
muzick
A high-performance, distributed music orchestration and recommendation platform.
Overview
muzick is designed to manage a local music library while providing an "infinite vibe" listening experience. It bridges the gap between a local filesystem and advanced discovery engines through a tiered recommendation architecture.
Tech Stack
Frontend
- Framework: React
- Routing: TanStack Router
- Data Fetching: TanStack Query (with Look-ahead Buffering)
- State Management: Zustand (for Session/Vibe state)
- Styling: CSS Variables (Customizable Themes)
Backend
- Runtime: Node.js / TypeScript
- Framework: Fastify
- Task Queue: BullMQ (via Redis)
- Search: Typesense
Infrastructure & Data
- Database: PostgreSQL (Source of truth for metadata, relationships, and session state)
- Cache/Queue: Redis
- Audio Analysis: Essentia (via Worker processes)
- External Metadata: MusicBrainz, Discogs, LRCLib, Cover Art Archive
Core Concepts
- The Rolling Vibe: A continuous, evolving stream of music that uses a "Rolling Window" of tracks. It interleaves owned library tracks with high-probability "probation" tracks (external discoveries).
- The Dislike Lifecycle: A multi-stage state machine that protects users from accidental deletions while ensuring the library stays clean.
- Tiered Similarity: Instant metadata-based matches, followed by deep audio-feature similarity.
Getting Started
Prerequisites
- Docker & Docker Compose
Running Locally
Vibe uses the same per-user identity convention as the rest of the API:
x-user-id when supplied, otherwise the local default user. Each user's Vibe
session and listening history are isolated from other users.
