Updated lrclib provider to include karaoke mode in the description and modes array.
📝 WalkthroughWalkthroughThe LRCLIB provider now retries lyric requests, parses LRCLIB ChangesLRCLIB karaoke support
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The change adds LRCLIB karaoke support, but the current implementation does not reliably expose karaoke results or parse all valid word timings, so affected lyrics may fail to display correctly. The PR is not merge-ready until the integration and parsing issues are fixed. Sequence Diagram(s)sequenceDiagram

🎯 Functional Correctness | 🟠 Major | 🏗️ Heavy lift
Complete the LRCLIB karaoke integration before enabling the mode. The current implementation has two correctness gaps:
Providers.jsdoes not callProviderLRCLIB.getKaraoke, so the parsed karaoke data is never assigned toresult.karaoke; exposeKARAOKEonly after that result is available.lyricsfileword mappings must be parsed independently of key order, including entries that begin withstart_ms. Sinceend_msis optional, derive a word's duration from the next word'sstart_ms, using the line'send_msfor the final word when present.
Please update the dispatcher and parser so all valid LRCLIB karaoke entries reach the runtime result.

i'm sorry if i did something wrong on the PR, i'm new to submiting them :) |
LRCLIB now supports karaoke lyrics with their API (https://lrclib.net/lyricsfile)
Also i made a little change to how lyrics-plus gets lyrics from LRCLIB. I made that when a request to LRCLIB fails, it removes the timestamps from the request, becouse if some lyrics from LRCLIB have a wrong timestamp, even 1 second, lyrics-plus will not display the lyrics.
