Widget:YoutubeAudio
From Scientolipedia
This widget shows an audio-only Youtube player to a wiki page.
It simply takes the video ID as the 'id' parameter, and optionally 'width' in px (default 250). Height is fixed as it is this that makes it an audio-only player.
You can see the widget in use here and here. These templates can be used in conjunction with this widget.
