I just started using cmus and it works great. Also loads up the music library pretty fast. tmux, neovim are great together (after some configuration.) Mplayer seems better than mpv. They need configuration though. htop/top are pretty useful for figuring out which applications are taking up cpu resources. cpufreq-utils are useful to set max/min cpu speeds if you're running low on laptop battery. meld is an amazing diff tool though not command line. vimdiff is useful too.
