Default Music from .MP4 [or any other video]

I'll repeat an older post I made, slightly more detailed.

MP4 (like most other video formats) is a container. It usually
contains a video stream and an audio stream, but it might contain
subtitle or other streams.

To determine exactly what streams your .MP4 contains, you need a tool
like Mediainfo Lite.

To determine the streams, yes; to do what the OP wanted (extract the
audio), no. Although what you've explained/described is a good way to do
it. But - given that the post was/is in Windows 'groups - I think the OP
would probably prefer a GUI method. (Of which I've posted three, and
others have others.) Granted, the three I use don't make it _obvious_
how to do an extraction without recoding, though I think they _can_.

You will find most music from YouTube and other sites is
****-awful in quality. Usually 96.0 kb/s. You can see that with
Mediainfo before extracting, of course, but Mediainfo gives you the
nominal value, Spek does a full analysis.

Depends what it is wanted for. For listening to on a variety of the
portable devices around now, 96k probably can be acceptable for some
material.
