The lyrics sibling of the Cover Art Filler, plus retag integration — reusing
the existing LyricsClient (LRClib) the import pipeline already uses.
- lyrics_client: extracted the LRClib fetch (exact-match-with-duration →
search fallback) into a shared _fetch_remote_lyrics, used by both
create_lrc_file (unchanged behavior) and a new check-only has_remote_lyrics.
- MissingLyricsJob (core/repair_jobs/missing_lyrics.py): scans tracks with no
.lrc sidecar and — Option A — only flags ones LRClib actually has lyrics
for, so instrumentals/interludes are never surfaced or re-flagged. Registered
in the job list; default OFF; respects the lrclib_enabled toggle.
- _fix_missing_lyrics (repair_worker): applies a finding by fetching + writing
the .lrc and embedding lyrics via create_lrc_file.
- Re-tag tool: new 'lyrics' setting ('fetch'|'skip', default skip). When
'fetch', apply_track_plans now also fetches/refreshes the .lrc per track
(fetch-if-missing, re-embed-if-exists) — threaded through scan gates, finding
details, the auto-apply path, and the manual fix handler. Settings UI
auto-renders the dropdown from setting_options; no markup needed.
- Frontend: type/action/result labels for missing_lyrics + a finding detail
render case.
Tests: 12 — has_remote_lyrics truth table, sidecar detection, scan (only-
fixable / skip-existing / lrclib-disabled), the apply handler, and retag
lyrics_action on/off. 694 repair/lyrics/cover/retag tests pass.
Discord report (netti93). The download flow runs `enhance_file_metadata`
(clears all tags) then `generate_lrc_file` (writes .lrc sidecar AND
embeds USLT). The retag flow only ran the first half — `enhance_file_metadata`
cleared USLT and there was no follow-up to restore it.
Two coordinated fixes (no new setting per kettui scope discipline —
user described it as "might even be an idea," consistency was the
load-bearing ask).
Fix 1 — retag calls generate_lrc_file after enhance
`core/library/retag.py:execute_retag` now invokes
`deps.generate_lrc_file` right after the `enhance_file_metadata`
call, mirroring the download pipeline. New `generate_lrc_file`
field on `RetagDeps`, defaults to None for backward compat with
any test caller that builds RetagDeps without it. Web_server's
`_build_retag_deps()` factory wires in the real
`core.metadata.lyrics.generate_lrc_file`.
Placement matters — runs BEFORE `safe_move_file` so the helper
sees the audio file at its current path with its existing sidecar
(which retag hasn't moved yet). After the embed, the audio file
gets moved with USLT now present; the sidecar move step that
follows is unaffected.
Fix 2 — create_lrc_file re-embeds from existing sidecar
`core/lyrics_client.py:create_lrc_file` used to early-return True
when an .lrc / .txt sidecar already existed (skipping the LRClib
fetch). For the retag case the sidecar is already there, so the
shortcut hit and USLT was never re-written. Now the helper reads
the existing sidecar and calls `_embed_lyrics` with its content
before returning. Empty / unreadable sidecars short-circuit
silently — defensive, no crash. Download flow unaffected because
no sidecar exists at fetch time.
7 boundary tests pin: existing .lrc triggers re-embed, existing
.txt triggers re-embed, empty sidecar skips embed, unreadable
sidecar swallows error, no sidecar falls through to LRClib (download
path regression guard), RetagDeps.generate_lrc_file field accepted,
field optional for backward compat.
Full suite: 3120 passed.
Stripped 4,200+ emoji characters from print(), logger calls across
39 Python files. Logs are now clean text — easier to grep, more
professional, no encoding issues on terminals without Unicode support.
Seasonal config icons preserved for UI display.
Plain (unsynced) lyrics were being saved with .lrc extension despite
having no timestamps, making them invalid for Plex and other players
that expect LRC format. Synced lyrics now write as .lrc, plain lyrics
write as .txt. Both types still get embedded in audio file tags.
Updated all file move/rename operations to handle .txt sidecars
alongside .lrc.
