Have mpegplayer use the mixer (the playback channel, since it's mutually exclusive to audio playback) so the clicks and skip beep can be used according to user settings. Introduce some system sound functions to make easier playing event sounds from various places and convert files calling 'beep_play' to use 'system_sound_play' and 'keyclick_click'. Event sound could be become themeable.
