I was thinking it'd be really cool if, when the CLI goes idle for more than 15 seconds or so, it can start redrawing the screen like a player, something like this (but prettier and with colors, obviously):
Lyrics

... (lyrics take up remaining screen height)

The bottom section would stick to the bottom of the screen.
When in this mode, the left key could be like the back button of a player, the right key the next button, and up and down would scroll the lyrics.
As soon as you start typing any other command, the normal CLI would resume.
Great idea from @dthree:
