This is a collection of scripts to manage LRC synchronized lyrics of songs playings in mpv. It provides keybindings to download the lyrics of the current song, and also scripts to create and synchronize lyrics yourself with vim on Unix-like systems.

lrc.lua

musixmatch-download

Downloads the lyrics of the currently playing song from Musixmatch's API.

The default keybinding is Alt+m, and it can be changed by binding script-message musixmatch-download

netease-download

Downloads the lyrics of the currently playing song from NetEase's API. It has more Japanese lyrics than Musixmatch.

NetEase's API doesn't return lyrics directly, but a list of matching entries. lrc.lua fetches the first 9, and if mpv's version is >= 0.39, it makes you select which one to download from the console, or download directly when there's only 1 match. Otherwise it downloads the first LRC whose album matches, or the first one if no entry's album matches.

While Musixmatch requires artist metadata, netease-download fallsback to querying by media-title if metadata is unavailable.

The default keybinding is Alt+n, and it can be changed by binding script-message netease-download

offset-sub

After adjusting sub-delay in mpv, this offsets the timestamps in the current subtitle file accordingly. It then resets sub-delay and reloads the subtitle track so you can offset it again if necessary. This works with any external subtitle and not just LRC. ffmpeg needs to be in PATH, or in the same folder as mpv on Windows, for this to work.

The default keybinding is Alt+o, and it can be changed by binding script-message offset-sub

Overlay

If mpv supports background transparency on your platform, you can display lyrics in a transparent overlay with --background-color=0/0 --ontop --input-cursor-passthrough.

Synchronizing lyrics

lrc.sh

This POSIX script fetches the metadata of the song playing in mpv, opens an LRC file with the same path as the song in $EDITOR, and opens $BROWSER, falling back to chromium if that is not defined, in the search page for the lyrics in the browser's default search engine. When it detects Japanese characters in the song path, it searches for lyrics in Japanese.

input-ipc-server=/tmp/mpv-socket is assumed for the mpv instance that plays music, and jq and socat are required.

When lyrics sites try to block copying text, you can inspect the HTML element with the lyrics and execute copy($0.innerText) in the console.

If the current song already has an LRC file, it doesn't overwrite it, but opens it in $EDITOR so you can quickly fix mistakes you notice while listening to the song. You can see the changes immediately with this vim autocommand:

autocmd BufWritePost *.lrc silent !echo sub-reload | socat - /tmp/mpv-socket

lrc.vim

This provides the following keybindings:

• F7 Prepend the current timestamp, with 0.3 seconds subtracted, to the current line. The 0.3 offset is fairly high and is chosen so that when you don't react immediately to a line you still have time to press F7 without having to seek backwards, but when you are ready to react immediately it is better to wait a little before pressing it.
• F8 Seek backwards 2 seconds.
• F6 Move the cursor to the current subtitle line.
• F5 Insert a timestamp equals to the one above minus 1/100th of a second in a blank line that is 2 lines above. When you have to synchronize a blank line between 2 lines with little delay between them, synchronize only the next filled line and use this.

It also increases scrolloff to keep the cursor in the center as you synchronize the lines.

To use this, add autocmd BufNewFile,BufReadPost *.lrc setfiletype lrc to your configuration file, then copy lrc.vim to ~/.config/nvim/ftplugin or ~/.vimrc/ftplugin.

https://github.com/vim-scripts/lrc.vim provides syntax highlighting. It errors because of carriage returns, but you can remove them with sed -i 's/\r//' lrc.vim
