I think through comments we've got a third solution:
Marcin Habuszewski: Is linking to YouTube allowed?
iandotkelly: By and large it is ok, as YouTube is a mainstream legal service and has a process for taking down copyrighted material. However if its is egregiously illegal - e.g. copies of whole movies this is discouraged.
iandotkelly: This question is specifically trying to discourage 'file downloads' not streamed content
iandotkelly: I'm not talking about copyrighted material in general, or linking in general - I'm specifically talking about binary file downloads. Practically "I'm trying to identify the TV show with this theme music - please follow this link and download this file to hear it
With all this in mind, we should tell the user to upload their audio/video clip to YouTube and link to it in their question, if it's illegal YouTube will remove it (and probably tell the user what they've "stolen" which will answer their question for them).
If they don't, we can close the question and remove the link.
