NaviMigrate

Spotify -> Navidrome playlist transfer tool in Go.

What it does

• Authenticates with Spotify using Authorization Code + PKCE (no client secret required).
• Fetches one or more Spotify playlists by URL/URI/ID.
• Searches for matching tracks in Navidrome using Subsonic search3.
• Creates matching playlists in Navidrome and adds matched tracks.
• Writes a JSON transfer report with unmatched tracks and errors.

Requirements

• Go 1.22+
• Spotify app client ID with redirect URI configured (default: http://127.0.0.1:8888/callback)
• Navidrome URL, username, and password

Build

go build ./cmd/navimigrate

Usage

./navimigrate \
  --spotify-client-id "<spotify-client-id>" \
  --navidrome-url "https://music.lofitrek.com" \
  --navidrome-username "test_user" \
  --navidrome-password "test_user" \
  --playlist-url "https://open.spotify.com/playlist/16DZpOTLqZvdbqxEavLmWk"

Useful flags

• --playlist-url "..." (repeatable): Spotify playlist URL/URI/ID
• --dry-run: resolve matches only, do not create playlists or add tracks
• --report transfer-report.json: report output path
• --concurrency 4: concurrent track match workers
• --spotify-manual-code=true|false: manual callback URL/code entry or local callback server

Navidrome self-test

Quick auth/search test without Spotify:

./navimigrate \
  --navidrome-url "https://music.lofitrek.com" \
  --navidrome-username "test_user" \
  --navidrome-password "test_user" \
  --navidrome-self-test

Write-path self-test (creates playlist, adds one track, then deletes playlist):

./navimigrate \
  --navidrome-url "https://music.lofitrek.com" \
  --navidrome-username "test_user" \
  --navidrome-password "test_user" \
  --navidrome-self-test \
  --navidrome-self-test-write
