usage: spotify [OPTIONS]

OPTIONS:
--play: Starts Spotify playing if it isn't already
--pause: Pauses Spotify if it isn't already
--playpause: Toggles Spotify between playing and pausing
--prev: Plays the previous song
--next: Plays the next song
--display: Prints the currently playing song and artist to stdout
--notify-send: Use only *after* --display; also pops up a notification with currently playing song and artist
--uri URI: tells Spotify to display URI (e.g. a playlist or user).

With no options, this script will kill a currently running instance of spotify if there is one.  With --uri, it starts Spotify iff it isn't running.  With any other option, it will return 1 if Spotify is not running.
