I am editing an existing release entry. The release dates back to 1994 but the label is still going on and it has a page for that release, where you can purchase a physical CD. I see no link type relation that appears to fit, namely, one that refers specifically to the label’s webpage for the release.
EDIT: This is the link for instance http://icehouserecords.com/gary-b-b-coleman-cocaine-annie.html
