I made a static page that points to the 78RPM collection, but it is more of a novelty than a real source of entertainment. Nobody would pay for these scratchy records! The content is here: https://www.locserendipity.com/PushPlay.html

The LPs from the Boston Public Library are a bit more interesting, but again none of this is going to even remotely compete with Spotify: https://locserendipity.com/LP.html

I do not host any of these, but just point to the URL at archive.org. Why can’t copyright holders use DMCA requests instead?
