I have it on anything random from my iPad. Includes the entire Dream Theater, Symphony X, and Rush discographies and most of Iron Maiden, a bunch of my original music, a bunch of ELP and Kansas, and all of Styx minus their few ballads.
Some mornings I wake up to "Tears" by Rush or "Far From Heaven" by DT, and some mornings it's "Inferno" by Symphony X or "Captain America" by Styx.
