not op, but you can host mp3s offsite (e.g. discord, catbox, etc. sadgrl has some useful links) and then link to them here with the html default audio player.
Im so sorry I didn't see this earlier, but you just get the html embed from youtube, and at the end of the url part, add "?autoplay=1". Then you just change the width and height to only a few pixels so that you can't see it.
using laptop and looks great :3
it looks good on my 1400 px display but ill check on my larger monitor when i have access!
Thanks! I don't have access to a larger monitor, so i've just been hoping my layout is good enough :')
