By now, you must have seen the custom made Super Mario World levels that require no player, no controller to pass. They simply let Mario and Yoshi do their thing, as buttons, switches and blocks boost them through each level. None of those user created levels are as impressive as this 11-minute monster, which uses the sound effects from those switch-hits and Koopa Troopa stomps to make beautiful music. My untrained ears can pick out but a few recognizable tunes—Mega Man 2 and Super Mario World, I don't know from Haruhi and Lucky Star—but song list help in the comments is more than welcome. Thanks to Spann for pointing us in its direction.
