I run the newest version of ubuntu server and it's pretty much adds for ubuntu pro. But to be honest I don't really mind it. They offer the extended updates for free for a handful of computers if you sign up for it. If the tradeoff for 10 years of support is some adds I am okay with it
I have been using g4 music and it works amazing and looks really nice on gnome https://flathub.org/apps/com.github.neithern.g4music
