Kumikyoku (InstanceTopic, 12)
From Compile Worlds
Kumikyoku is an eleven-minute (or ten and a half excluding the talking at the end) remix of several well-known (and otherwise) songs from anime and video games. It's widely considered to be the best remix ever (though Ryuuseigan would like to argue with that), and is also known as the Japanese national anthem due to how epic it is.
