Do you agree that Mozart couldn't compose anything as good as Bad Romance?

I was reading the Gaga Forums and I came upon this thread posting a parody video saying that Bad Romance was plagiarized from a Mozart composition in 1783, a href="http://www.youtube.com/watch?v=650r-bU7TNM," rel="nofollow"http://www.youtube.com/watch?v=650r-bU7T…/a the posters on the thread a href="http://www.ladygaga.com/forum/default.aspx?tid=448828&cid=594" rel="nofollow"http://www.ladygaga.com/forum/default.as…/a said that Mozart couldn't compose anything as good as Bad Romance and that Clical Music is dead, do you agree?
