Osu - Future Will Lead & The Ray of Light 6.03* (FREE 6 STAR!)
This map has got to be one of the easiest if not the easiest 6* I have ever played, I would't even call it a hard 5*. It's just so nice and calm pretty much throughout the song, even the fact that its 5 mins long doesn't add difficulty since the map isn't that hard in the first place.
