Deletion of Metallica demos

Comment: to Metallica discography.  I'm convinced by TPH's argument that demos are not notable even if by a notable act; but notability deals with whether something should have a separate article.  It does not deal with whether the content should be d, and indeed in this case it should.  Further, "Metallica demos" is a very, very plausible search term and I am strongly of the opinion that plausible search terms should not be redlinks on Wikipedia
