Deletion of Hero (X Factor release)

Comment: Note I am the editor who split the articles. There was a brief discussion on the talkpage about this during a separate discussion about an edit-war. (well I said I was going to do it and no-one objected.) This is an extraordinary cover that is taking an extraordinary amount of space in the original article: a cover version is not relevant to the original artist. A cover that sells 500,000 copies is notable in its own right. This cover has received a lot of media attention, meets general |notability requirements, is |verified and I see no reason to delete this article

Comment: There should be some sort of policy for covers, as this issue keeps coming up all the time.  Someone already mentioned Run (Snow Patrol song), notably covered by Leona Lewis.  Current Wikipedia ''consensus'' dictates that articles are for songs, not for versions.  No, it is '''not policy''', and nowhere does it say in  or  to do so.  However, if this changes (for example, if it becomes policy to write separate articles for different versions or covers), then a very strong line has to be drawn.  It should be obvious that one-time performances or album tracks shouldn't merit their own articles (i.e., "Last Christmas" redone by Ashley Tisdale or Billie Piper), but what about covers that charted?  Or charted well?  Or, in this case, went #1

Comment: The cover charted #1 in two different charts, which makes this independently notable according to . Also, there is sufficient material to sustain a separate article. Keeping this tucked in the original article gives too much weight to material that isn't actually by Mariah Carey in an article about her version of the song
