There are so many options, but since I assume it would be your first linux, I’d start with something that just works at once and does everything you say you need in your comment. Zorin OS will just work at once (I might not prefer this dist myself, but I’m 20 years in the linux game… this is a distro that just works really well for first timers, and it’s a good distro).

1. Download the free Zorin OS Core version (it’s the full OS with no limitations).
2. Download Etcher.
3. Put a USB drive (min 4GB) in your computer, start Etcher and select the Zorin OS file (image) you downloaded and select the USB you put in your computer, press “Flash!”. Wait for it to finish.
4. Restart computer and boot from the USB drive (usually, right after your computer restarts, you press F9 repeatedly)
5. Fallow instructions and when done installing, restart and; you’re free from Windows!
6. Enjoy!

Do the phones have guns…?

If you want to understand your setup (which is quite important, in my opinion), there is no way around the fact that you will have to spend some time reading about the services you use. Even if you GUI everything away, it will come a moment when something breaks and you stand there, knowing nothing and/or what to do/where to begin. Most people aren’t in for the “reading” part.

Qmmp has that option in the settings.

Ardour, and also what LoopDigger said.
