;;; Commentary:
;; This file provides an interface to retrieving comments from

;; To activate, put something like this in your ~/.emacs:
;; (require 'emms-info-ogg)
;; (add-to-list 'emms-info-methods-list 'emms-info-ogg-comment)
;; You'll of course need to also have a player if you want to actually
;; play the files.
