For those on Jellyfin, there’s a plugin that can pull lyrics from lrclib. Not sure how it exactly compares to this, but it works for me.

I know there are different use cases for each, but generally do people prefer self hosted nextcloud, proton docs, or libre office?

I have no issues with Jellyfin + Symfonium, but I also cache my songs offline. I almost never play a track that hasn’t been downloaded.
