@ᔕᖺᘎᕊ I think that would do the trick since the permissions are already there, and I'd try to hack it in myself if I had more JS experience. I'd be happy to test anything you come up with!

@TimStone I looked for an update here first in the post text and didn't see one, so no. I will update now, thanks!

This script appears to have been broken recently; from the timing I suspect by SE's recent jQuery update: meta.stackexchange.com/questions/284996/… (See? I shouldn't be able to post a bare link like that. ;)

@ᔕᖺᘎᕊ I figured out the fix (wasn't much, but my JS is meh), so I'm enjoying it on my moderator account now. I've provided it above so you can poke it to verify when you have time to mock up some moderator-account-HTML inputs. Thanks! And good luck with your studies!

@ᔕᖺᘎᕊ I totally understand! Thanks for the great userscript, in the meantime.

This appears to no longer work. The presets are broken since or.sstatic.net is no longer in use, and entering a url to an MP3 doesn't do anything. Everything just gives the default sound.
