When I first switched to Linux, I needed to find a suitable alternative to AIMP on Windows.

At the time I was running Fedora Workstation, so I first tried options that fit the GNOME desktop. The libadwaita apps I tried (G4Music, Amberol, etc) all suffered similar issues to do with shuffle, where it wasn't able to just go to a random track, instead ordering all the tracks randomly once and having a fixed queue. Amberol in particular had bad shuffling, only randomising all the tracks below the one currently playing (so the ones above are unchanged, which is stupid I think). I ended up using Tauon, which had a workable shuffle but admittedly less nice UI. I also remember that Tauon was not very configurable.

Next, I switched to KDE Plasma, so I ended up using Elisa, which fit the KDE desktop, had nicer UI than Tauon, but suffered from the same shuffle issue as the libadwaita apps, so I had to occasionally reshuffle the music to get consistently random tracks.

Having recently switched to EndeavourOS and really getting into the weeds of command line stuff, I decided to try using MPD and the client RMPC (suggested by Bread on Penguins). For god knows what reason, it's the only option that has proper good shuffle that's just randomly going to each track (besides Tauon and, on Windows, AIMP), and it is easily the most customisable. RMPC has excellent documentation making changing the configs super easy!
