Whether it looks professional or not is not for you to decide. I am following the Wikipedia guidelines. I belive you were the one (maybe it was Gwenol) who told me that the actual title of the article did NOT have to match the subject. A song title is a proper work of art and is capitalized by the artist in a particular way. There are no guidelines stating naming conventions within articles. If you still disagree, I think we should have a third party administrator address the issue, because I am definetely not breaking any Wikipedia rules.
