-;;; Jorgen has the following to say about playlist-mode:
-;;;
-;;; Playlist Mode
-;;; =============
-;;; This should be a file named emms-playlist-mode.el, providing said
-;;; mode, which is a suitable value for `emms-playlist-default-major-mode'.
-;;;
-;;; The mode should probably set `emms-playlist-buffer-name' and
-;;; `emms-playlist-insert-track-function', and add something to
-;;; `emms-playlist-selection-changed-hook' and
-;;; `emms-playlist-cleared-hook'.
-;;;
-;;; When this is done, emms-pbi.el, emms-pbi-filter.el,
-;;; emms-pbi-mark.el, emms-pbi-popup.el and emms-pl-manip.el can be
-;;; removed.
-;;;
-;;; ...and when Jorgen says (require 'jump) we say how-high.el.
-;;;
 ;;; I'm designing this as a method of displaying and manipulating the
 ;;; different Emms playlist buffers defined by the user.
