Tube Au3

Tube AU is a web video player audio unit plugin.
The plugin user interface looks like an ordinary web browser, except that it is limited to viewing only YouTube, and that the audio stream is sent to the plugin output rather than going directly to the speaker.
Note that this is an audio unit plugin only; it does not run as a stand-alone app.
