Navidrome can do lyrics now - but how?

With v63, audio streamer Navidrome finally got full lyrics support. I just wanted to try it out and fell flat on my face because… well, not even the official docs say anything about lyrics. Also, I’m not too familiar with how lyrics are added to songs in general. So my questions are these:

1. How can I add any lyrics to my songs so the web client will display them?
2. What formats would you recommend sticking with? (TTML, ELRC, SRT, YAML, LRC, or even TXT)
3. Is there a way to automate adding lyrics in bulk (instead of tedious manual work)?

github.com/navidrome/navidrome/releases/tag/v0.63.0

I’m personally going with elrc where available, otherwise lrc.

The E in ELRC stands for enhanced. It has karaoke-style granularity, if that’s something you care for, and can find.

Navidrome has supported lyrics for a while now, but the web client only supports embedded ones. Checked my instance and that still seems to be the case as most of my songs have lyrics as standalone files, but the client insists that there aren’t any lyrics.

With the update I’ve added this Navidrome lyrics plugin, but I’ve not really tested it yet. I’ve been using lrcget to locate and add lyrics before this update.

Lyrics work fine in other clients. On my phone I’ve been experimenting with NaviBeat, otherwise I’ve been using Amperfy.

On desktop I’ve been using Nocturne, (via flathub), but I think based on how long lyrics take to load in that, that it fetches the lyrics from somewhere other than Navidrome.
