As a user visiting for the first time, I should be greeted with a random song after 5sec of inaction

Run a demo command command that displays the basic player commands and loads a random playlist.

Feeling indecisive, aye? Let me play something for you...

{load random playlist}

If you don't like this song, simply type `next` and hit enter.
Do you want to skip ahead? Run `skip 5` to skip ahead five, or any number of seconds.
Would you like a list of the songs in this playlist? Run `ls`.

If you want to see a list of all playlists, run `cd ..`, and then run `ls`.
To select a playlist from the list, run `cd name-of-the-playlist`.
To play the selected playlist, simply type `play`
