The downloads page previously showed only title and source per download. Now shows album artwork thumbnail, artist name, album name, source badge, and quality badge (after post-processing). All metadata comes from the existing matched_downloads_context — no extra API calls needed. Falls back gracefully to title-only display when context metadata is not available (e.g. orphaned Soulseek transfers with no task mapping). |

SoulSync - Intelligent Music Discovery & Automation Platform
Spotify-quality music discovery for self-hosted libraries. Automates downloads, curates playlists, monitors artists, and organizes your collection with zero manual effort.
IMPORTANT: Configure file sharing in slskd to avoid Soulseek bans. Set up shared folders at
http://localhost:5030/shares.

What It Does
SoulSync bridges streaming services to your music library with automated discovery:
- Monitors artists → Automatically detects new releases from your watchlist
- Generates playlists → Release Radar, Discovery Weekly, Seasonal, Decade/Genre mixes, Cache-powered discovery
- Downloads missing tracks → From Soulseek, Deezer, Tidal, Qobuz, HiFi, YouTube, or any combination via Hybrid mode
- Verifies downloads → AcoustID fingerprinting for all download sources
- Enriches metadata → 10 enrichment workers (Spotify, MusicBrainz, iTunes, Deezer, Discogs, AudioDB, Last.fm, Genius, Tidal, Qobuz)
- Tags consistently → Picard-style MusicBrainz release preflight ensures all album tracks get the same release ID
- Organizes files → Custom templates for clean folder structures
- Manages library → Plex, Jellyfin, Navidrome, or SoulSync Standalone (no media server required)
- Scrobbles plays → Automatic scrobbling to Last.fm and ListenBrainz from your media server

Audio Verification
AcoustID Fingerprinting (optional) — Verifies downloaded files match expected tracks
- Runs for all download sources (Soulseek, Tidal, Qobuz, HiFi, Deezer, YouTube)
- Catches wrong versions (live, remix, cover) even from streaming API sources

Metadata & Enrichment
10 Background Enrichment Workers: Spotify, MusicBrainz, iTunes, Deezer, Discogs, AudioDB, Last.fm, Genius, Tidal, Qobuz
- Each worker independently processes artists, albums, and tracks

- Error items don't auto-retry in infinite loops (fixed in v2.1)
Multi-Source Metadata
- Primary source selectable: Spotify, iTunes/Apple Music, Deezer, or Discogs
- Spotify no longer auto-overrides — user chooses their preferred source in Settings
- Spotify auth still enables playlists, followed artists, and enrichment
- MusicBrainz enrichment with Picard-style album consistency
Post-Processing Tag Embedding
- Granular per-service tag toggles (18+ MusicBrainz tags, Spotify/iTunes/Deezer IDs, AudioDB mood/style, Tidal/Qobuz ISRCs, Last.fm tags, Genius URLs)

Advanced Matching Engine
- Version-aware matching: strictly rejects remixes when you want the original (and vice versa)
- Unicode and accent handling (KoЯn, Bjork, A$AP Rocky)
- Fuzzy matching with weighted confidence scoring (title, artist, duration)
- Album variation detection (Deluxe, Remastered, Taylor's Version, etc.)
- Streaming source match validation: same confidence scoring applied to Tidal/Qobuz/HiFi/Deezer results as Soulseek
- Short title protection: prevents "Love" from matching "Loveless"

Unraid
SoulSync is available as an Unraid template. Install from Community Applications or manually add the template from:
https://raw.githubusercontent.com/Nezreka/SoulSync/main/templates/soulsync.xml
PUID/PGID are exposed in the template — set them to match your Unraid permissions (default: 99/100 for nobody/users).
Python (No Docker)
git clone https://github.com/Nezreka/SoulSync
cd SoulSync
pip install -r requirements.txt
gunicorn -c gunicorn.conf.py wsgi:application

For local development and tests:
pip install -r requirements-dev.txt
pytest
gunicorn -c gunicorn.dev.conf.py wsgi:application
Setup Guide
Prerequisites
- slskd running and accessible (Download) — required for Soulseek downloads
- Spotify API credentials (Dashboard) — optional but recommended for discovery
- Media Server (optional): Plex, Jellyfin, or Navidrome
- Deezer ARL token (optional): For Deezer downloads — get from browser cookies after logging into deezer.com
- Tidal account (optional): For Tidal downloads — authenticate via device flow in Settings
- Qobuz account (optional): For Qobuz downloads — email/password login in Settings
Step 1: Set Up slskd
SoulSync talks to slskd through its API. See the slskd setup guide for API key configuration.
- Add an API key in slskd's
settings.ymlunderweb > authentication > api_keys - Restart slskd
- Paste the key into SoulSync's Settings → Downloads → Soulseek section
Configure file sharing in slskd to avoid Soulseek bans. Set up shared folders at http://localhost:5030/shares.
Step 2: Set Up Spotify API (Optional)
Spotify gives you the best discovery features. Without it, SoulSync falls back to iTunes/Deezer for metadata.
- Create an app at developer.spotify.com/dashboard
- Add Redirect URI:
http://127.0.0.1:8888/callback - Copy Client ID and Client Secret into SoulSync Settings
More detail in Support/DOCKER-OAUTH-FIX.md.
Step 3: Configure SoulSync
Open SoulSync at http://localhost:8008 and go to Settings.
Download Source: Choose your preferred source (Soulseek, Deezer, Tidal, Qobuz, HiFi, YouTube, or Hybrid)
Paths:
- Input Folder: Container path to slskd's download folder (e.g.,
/app/downloads) - Output Folder: Where organized music goes (e.g.,
/app/Transfer) - Import Folder: Optional folder for importing existing music (e.g.,
/app/Staging)
Media Server (optional): Use your machine's actual IP (not localhost — that means inside the container)
Step 4: Docker Path Mapping
| What | Container Path | Host Path |
|---|---|---|
| Config | /app/config |
Your config folder |
| Logs | /app/logs |
Your logs folder |
| Database | /app/data |
Named volume (recommended) |
| Input | /app/downloads |
Same folder slskd downloads to |
| Output | /app/Transfer |
Where organized music goes |
| Import | /app/Staging |
Optional folder for importing music |
Important: Use a named volume for the database (soulsync_database:/app/data). Direct host path mounts to /app/data can overwrite Python module files.
