Add another vote for "Radar Love"... funny how many thought of that, is it just an artifact of FM rock playlists?
For me some special ones are:
Peter Gabriel's version of the "Weavers Reel" from Ovo, "The Rhythym of the Heat" and "The Famiily and the Fishing Net" from Security.
Iron Maiden's "Number of the Beast" followed up by "Run to the Hills" on the original album.
Portions of Rick Wakeman's "Six Wives of Henry the Eighth",
Emerson Lake and Palmer's version of "Jerusalem" on Brain Salad Surgery (Tocatta and Karn Evil 9 too...)
Roger Waters' "The Powers That Be" from Radio KAOS (+whole album)
Queen's "The Prophet's Song" from A Night at the Opera
Dire Straits' "The Man's too Strong" from Brothers in Arms and "Iron Hand" from On Every Street
GnR's "Don't Damn Me" from Use Your Illusion I
Hendrix's "Manic Depression" followed up by "I Don't Live Today" (oh yeah!)
Any of Tristania's work
I think most of these songs can be blamed for the heat damage to my old engine! (105 hp is just not meant to break 180 kph on hilly, twisty, bumpy roads...
)
