But yeah, another song by Bjork, "Hunter," also has a lot of bass, but I remember "Hyper-Ballad" more vividly being overwhelming on an older iteration of my father's system. I'll have to try out both songs. I don't know if I have any other music that will really exercise the lower end like those two songs. Maybe some Bach. But yeah, I'll also be trying out a lot of movies. Appleseed, Lord of the Rings, The Incredibles, Finding Nemo, King Kong, Sky Captain and the World of Tomorrow, and the opening song of Ghost in the Shell. The scene with the thunder in Apocalypto might also be cool. Fun, fun, fun.
