No, it's not. It might have taken me eight years (on-and-off) to beat
Super Mario World to 100% completion, but I can assure you, there is no instance of a "Queen" stage, or an entire Ozzy Osbourne level.
This video, along with many others like it, are created using ROM hacks that allow the user to build a SMW stage however they would like it, from fairly simple to impossibly complex, with or without the original background music still intact.
