All I've got so far is kiwi6 or owning your own domain to host files.

communism maybe? I've tried soundcloud, lastfm, 8tracks, etc, but tbf I also don't know the sites super well so maybe I'm missing something.

mediafire maybe?

ummm Box | Secure Content & Online File Sharing for Businesses maybe? idk what you want it hotlinked for?

To embed it with the <audio> tag

So the direct link has to actually end in ".mp3" or whatev

ohhhhh

ok yeah i have no idea sobs. maybe the box though??? i know you can listen to mp3s that get uploaded on it

Thanks!
