I agree that the term “discography page” would be misleading, but the actual term is “discography entry” (so the ticket has a misleading title).
In this case the page is not in the context of any particular release or artist.
Perhaps an equivalent term might be “opus entry”. This would also imply that an artist (composer) could have an “opus page” as an external link to a page containing a listing of all their works.
