I use mpv. It's primarily meant as a video player but it works well for music too and even as an image viewer (alternative to 'feh') There is a pretty active community of people writing scripts for mpv (Lua or JS) and it's generally really nice for users with a hacker ethos. I consider it the Emacs of multimedia. (I wouldn't recommend it for casual users, I tell family members to use VLC.)
