No... USENET often called simply 'newsgroups' is a 'bulletin board'. Many are text only, but many also allow 'binaries'... music and images and videos.

At one time one called alt.binaries.sounds.MP3.folk had LOTS of posts, and some places would archive posts for several years. Because of so many other venues, USENET has largely faded. The last post was July 10 of some stuff by Norman Blake.

So... I have a Dropbox folder. I will try soon to post the 5 songs I have there. I'll put up a link when I've done it. (You really ought to get a regular Mudcat membership so this could all be done privately)
