Thanks!

Emms contains code to be able to plug in code as you have written.

Defining a new simple command player is easy:

(define-emms-simple-player pausing-mplayer '(file url)
  (regexp-opt '(".ogg" ".mp3" ".wav" ".mpg" ".mpeg" ".wmv" ".wma"
                ".mov" ".avi" ".divx" ".ogm" ".asf" ".mkv" "http://";))
  "mplayer" "-slave")

You can then add functionality to that player:

(emms-player-set emms-player-pausing-mplayer
                 'pause
                 'emms-player-pausing-mplayer-pause)
                 ; ^ I want a prize for that function name!

Which can be used easily:

(defun emms-pause ()
  "Pause the current player."
  (when emms-player-playing-p
    (funcall (emms-player-get emms-player-playing-p 'pause))))

etc.

The rest of the player then has to be made aware of the "paused"
state, but emms does not care otherwise. :-)

I haven't found the "repeat this track" one too useful. If you
have working code, please submit it, we will add it to CVS
(probably in a new file). :-)
