I'll have more later, but just to get you started:
Judas Priest- Breaking the Law and Heading out to the Highway
Iron Maiden-The Trooper
Dream Theater-Overture 1928, The Spirit Carries On, The Count of Tuscany, On the Backs of Angels
Joe Satriani-Flying in a Blue Dream
AD/DC-Rock and Roll Train and War Machine
Black Sabbath-Neon Knights, Heaven and Hell, The Mob Rules, Slipping Away
Queenstown-The Lady Wore Black, Eyes of a Stranger...
Ooops! Maybe I should have said "it depends on how long your trip is going to be!"
Anyway, those are some of MY favorites to listen to while driving...
