+# add-synced-lyrics
+A script that automates adding lyrics to your songs.
+```
+add-synced-lyrics.sh [options]
+
+OPTIONS:
+  -d, --dir       process files in directory
+  -r, --recurse   recursively process directory
+  -f, --file      process one file
+  -e, --embed     embed lyrics directly into the song file
+  -n, --dry-run   do not add synced lyrics,
+                  just show the files that would be processed
+  -i, --ignore    ignore errors, and continue attempting to find lyrics
+                  even in the case of errors
+  -h, --help      show this output
+  --debug         extra information useful for debugging
+  --eval          output bash functions that can be directly processed
+                  by eval for use with testing this script.
+```
+
+# Requirements
+- CLI tools:
+    - coreutils: `mktemp cat sort base64 readlink`
+    - `ffmpeg ffprobe` 
+    - `jq`
+    - `node` (any version)
+    - [`librelyrics`](https://github.com/libre-lyrics/librelyrics):
+        - uses the [deezer](https://github.com/libre-lyrics/librelyrics-deezer) and [spotify](https://github.com/libre-lyrics/librelyrics-spotify) plugins
+    - [`spotify`](https://github.com/ledesmablt/spotify-cli) most easily installed with `uv tool install --python 3.8 spotify-cli`
+- Music that has the appropriate ISRC tag.
+
+## Features
+- Uses the ISRC tag to search for synced lyrics across the download providers: lrclib, spotify, and deezer (in that order).
+- Caches all networked-calls to the download providers.
+- Supports separate (dedicated .lrc file) or adding the lyrics directly to the song file with the LYRICS tag.
