So I self host all my music via Plex and for some artists and albums Plex (via Plex pass I believe) pulls lyrics and can show you like Spotify etc but some artists are not supported/popular. I found a couple apps that ‘worked’ to download lyrics but the best one was this https://github.com/tranxuanthang/lrcget
Just thought I would share for others who would want to do the same I have a large library and adding lyrics was not hard at all and found most out of the gate. If you have other solutions I would love to hear about them maybe they are better lol
It adds the file as same name in same folder that song is located
Looks like it’s intended to be used interactively from your desktop.
