I'm a fan of the classics, so usually I listen to a lot of Rush, mostly the old albuns like Farewell to Kings, 2112 and Moving Pictures. Also a fan of Led Zeppelin, The Yardbirds, Queen and so on.
When I'm flying I like to some jazz, like Tina Brooks and Miles Davis. If I listen to Rock while flying I get too careless and my engineer starts cursing me for charging a galleon Broadside with my squid while humming Fly by night.
