Still shown to the user, but should be flagged as possibly wrong. - 'none': no meaningful relationship — e.g. a completely different artist AND a title that only coincidentally shares a common word (Queen's "We Will Rock You" for Tiny Tim's album "Rock").

Never returns the other type. Returns {"url": None} if nothing plausible is found — we'd rather report no match than confidently show a wrong one.
