LRX-CLI

A CLI tool for fetching LRC lyrics on Linux. Automatically detects the currently playing track via MPRIS/DBus and retrieves the best-matching lyrics from multiple sources, ranked by confidence scoring.

Sources

Sources are queried in order. High-confidence results (exact match or manual insert) terminate the pipeline early; otherwise all sources are tried and the highest-confidence result wins.

1. Local — sidecar .lrc files or embedded audio metadata (FLAC, MP3)
2. Cache Search — fuzzy cross-album lookup in local cache
3. Spotify — synced lyrics via Spotify's API (requires SPOTIFY_SP_DC and Spotify trackid)
4. LRCLIB — exact match from lrclib.net (requires full metadata)
5. Musixmatch (Spotify) — Musixmatch API with Spotify trackid (requires MUSIXMATCH_USERTOKEN and Spotify trackid)
6. LRCLIB Search — fuzzy search from lrclib.net (requires at least a title)
7. Musixmatch — Musixmatch API with metadata search (requires MUSIXMATCH_USERTOKEN and at least a title)
8. Netease — Netease Cloud Music public API
9. QQ Music — QQ Music via self-hosted API proxy (requires QQ_MUSIC_API_URL that provides the same interface as tooplick/qq-music-api)

I'm aware that Spotify's lyrics are provided by Musixmatch, but the fact is that Musixmatch's own search will yield different (and more) results than Spotify's, so I treat them as separate sources.

Usage

See lrx --help for full command reference. Common use cases:

• Fetch lyrics for the currently playing track:

  lrx fetch
  

  targeting a specific player and a source to fetch from:

  lrx --player mpd fetch --method lrclib-search
  

• Search by metadata (bypasses MPRIS):

  lrx search -t "My Love" -a "Westlife"
  lrx search --trackid "5p0ietGkLNEqx1Z7ijkw5g"
  

  or by path to a local audio file:

  lrx search --path "/path/to/Westlife - My Love.flac"
  

• Export to sidecar .lrc file (or .txt with --plain):

  lrx export
  lrx export --plain
  lrx export --output /path/to/lyrics.lrc
  

• Cache management:

  lrx cache stats                    # statistics with source×status table and confidence distribution
  lrx cache query                    # inspect cache entries for current track
  lrx cache clear                    # clear cache of current track
  lrx cache clear --all              # clear entire cache
  lrx cache confidence spotify 100   # manually set confidence for a source
  

Configuration

Set credentials via environment variable or .env file:

• ~/.config/lrx/.env — user-level
• .env in working directory — project-local
• Shell environment — highest priority

SPOTIFY_SP_DC=your_cookie_value
MUSIXMATCH_USERTOKEN=your_musixmatch_usertoken
QQ_MUSIC_API_URL=https://api.example.com
PREFERRED_PLAYER=spotify

• SPOTIFY_SP_DC — required for Spotify source. Defaults to empty (disabled Spotify source).
• MUSIXMATCH_USERTOKEN — required for Musixmatch sources (Curators Settings Page -> Login (if required) -> "Copy debug info")
• QQ_MUSIC_API_URL — required for QQ Music source. Defaults to empty (disabled QQ Music source).
• PREFERRED_PLAYER — preferred MPRIS player when multiple are active. Defaults to spotify. Only used when no --player flag is given and more than one player (or none of them) is currently playing.

Shell completion (zsh/fish/bash):

lrx --install-completion
