Is there any benefit to using your own Last.fm API key?
I've made a Last.fm API key but at the point of adding it to Navidrome I wondered why I was bothering; is this option only there because of backwards compatibility or is there a tangible benefit?
Yes, that's why there's a Last.fm API key, but that and scrobbling work out of the box with the default key. So, is there any reason to replace it with a personal one?
