Unless they didn’t enable file extensions to actually show, so an “.nfo” could actually be a “.nfo.exe”.
It does not seem to be the case here, but I really would be careful with double clicking untrusted files. Opening them through a media player directly is a much safer option.
Interesting. I’ve had a worse experience with my music library because of how Navidrome didn’t support multi artist tags properly until recently. But while writing this comment, I checked again and they merged it in 0.55.0!
So I’d recommend giving Navidrome a try too. Symfonium is a great client.
