NYT apostrophe

From the New York Times online, a link on the front page (as it were):

The Smith's Music, on Stage

That should be Smiths', plural possessive.

This goof and others (this one, for instance) suggest that writing errors are filtering ever upward.

Update: The error on the Times page has been corrected. Is the paper catching its (not it's) own mistakes? Responding to e-mail corrections from readers?
