@bumbervevo to play music I use cmus, and ranger as file manager (runs on python). You may prefer nnn or other compiled text-based browsers. The only terminal-based browser I know is w3m, I think that's the name. You can also use Emacs in a terminal, if you install it with the GUI you can still force the terminal mode by executing "emacs -nw", which makes it a little faster, and can be used as a file manager, text editor, media player, and browser.
