My top 5 ( just for now :D )
Under the Glass Moon - Dream Theater
Paradise City - Guns and Roses (the outro is nuts, I think the fastest by Slash)
Devil Takes the Hindmost - Allan Holdsworth
Blitzkrieg - Yngwie Malmsteen (some very hard passages, one of Yng's best)
Desert Rose - Eric Johnson
Guitarplaying is 1 Percent Inspiration, 99 Percent Perspiration... :)
