+Enabling/disabling Progress Tracking
+------------------------------------
+
+By default, emus uses the mpg123 output to keep track of the progress
+through a track, and to listen to Icecast stream updates. However,
+this can cause glitches in the audio on some systems if Emacs (running
+in GUI mode) looses focus for extended periods. As a work-around it is
+possible to toggle progress tracking using `M-x emus-progress-tracking`
+which, inside the browser, is bound to `!`.
