What is /objectively/ the best music player?
Foobar can be amazing if you're any good with writing/modifying scripts to get it skinned just right. Musicbee is solid out of the box, but lacks customization. I've also heard good things about MediaMonkey.
mpd + ncmpcpp
It just works and means I can organise my music myself and browse it just via directory structure. Only extra feature I'd like would be able to rate stuff so if I listen to a single song and like it I can find it again.
Does it have a library organizer, or is it just by-folder view?
I was using mocp for some time, but was too lazy to organize the music, so folder navigation was tiring, so I switched to Clementine, which I keep in a separate tag, but sometimes feel as if having a small player in a terminal window would be quite cool.
