Well I guess you could say "as long as the final output is an audio file"...

But I hope there's nothing else too loophole-y if we say that

Tried making a Stack Snippet but it didn't seem to be working, might try again later

@Sp3000 did you find some post on music.SE or AV.SE that has embedded music?

@Sp3000 relevant meta.music.stackexchange.com/a/246/17058

hm, I can't upload to SoundCloud for some reason... says I need to confirm my email address first (which I did)... maybe it just takes some time

hm "Uncaught SecurityError: Failed to read the 'cookie' property from 'Document': The document is sandboxed and lacks the 'allow-same-origin' flag."

I'll try when I get back home - was merely trying the embedding code from Soundcloud earlier

yeah that's what I did, but it didn't work either

I also copied the HTML from a player embedded on music.SE and that also didn't work (no error, just nothing happened)

I'm really looking forward to someone answering this challenge in CSound or something like that.

has there been any progress? when will the question be out?
