Linux

I stopped using iTunes around 2012 and I expect its design has changed quite a bit, since then; Banshee was a perfect capture of it, then, and I haven't been able to find a suitable replacement for Banshee since development halted on it.

Granted, the most important qualities, for me, is for the player to allow tagging within the app. and to rename and organize the files by their tags automatically once those tags have been modified and every Linux developer seems to hate that so my unique requirements seem to largely drive my impediment.
