LazyDaisy (she/her)

first of all, there appears to be a fork of Cantata (which is still my music player of choice as well) that is still getting updates (maintained by a one nullobsi), if you’re on Arch, it’s available on the AUR as cantata-qt6
my current fallback option for local music playback is fooyin, I don’t know for certain whether it checks all of your boxes at the moment, but it is still very much in active development
I also use jellyfinmediaplayer for music on my jellyfin server, but that doesn’t have lyric support (unfortunately)

I’m personally fond of Sway and Kitty

I’m currently using TimeShift to backup my desktop onto an external hard drive (the why is because of how simple it is to use) and I’ll be making a copy of anything I upload to my jellyfin server onto the external hard drive as well. I hope to eventually have a dedicated backup server and have a duplicate of it at a friend’s house for offside backup too
