Hi. I recently published my app on Flathub and have been steadily updating it to make it better.
With it you can download Music from Youtube and tag it to create a beautiful collection of local Music. Check it out: https://flathub.org/apps/net.fhannenheim.musicfetch
Also, CLI apps are not that great on phones. I like CLI on a desktop computer, but on my Debian phone I prefer GUI.
