Nothing wrong with that! I prefer Inter for nearly all UIs these days, but I still think Segoe UI looks better than GNOME’s current default of Cantarell.

Nice writeup, thanks for sharing. For your music woes, have you tried plain old VLC? It’s what I use for music (and Mpv for video) and it’s been fine. I like that I can keep my mp3 folder structure the way I like it and still be able to browse and queue albums without relying on metadata.
