A lot of games are compatible through a program called wine, but you usually need some amount of skill in order to use it. Also consider Proton, it's originally a program from SteamOS, an official Linux distro made by Valve.

Games using kernel level anticheat are almost never compatible even through wine and proton. I'm not into gaming though, that's just what I've heard.

There is a music player called Astra, it is currently in beta, but it seems to be worth trying out.

For sure you should try installing Linux to a non-main PC, that's what I've done too.
