After reading Phil's list, I figured I should put mine out there. Of course, I had to pick myself off the floor and wait for the laughing cramps to subside. I know the list won't be as ecclectic as Nathan's or John's, but I think it's pretty good. Of course, I know it's only supposed to be 5 songs, but I just couldn't help myself. I have marked my ultimate top 5 in bold.

• Zoo Station - U2 (Achtung Baby)
  
• Welcome to the Jungle - Guns N' Roses (Appetite for Destruction)
• Thunder Road - Bruce Sprinsteen (Born to Run) This album also has one of my favorite last songs of all time in Jungleland.
  
• Don't You (Forget About Me) - Simple Minds (The Breakfast Club Soundtrack)
• One Headlight - The Wallflowers (Bringing Down the Horse)
• Speak to Me/Breathe - Pink Floyd (Dark Side of the Moon)
• Beds are Burning - Midnight Oil (Diesel and Dust)
• Possession - Sarah McLachlan (Fumbling Towards Ecstacy)
• I Don't Care Anymore - Phil Collins (Hello, I Must Be Going!)
• Hotel California - The Eagles (Hotel California)
• Vertigo - U2 (How to Dismantle an Atomic Bomb)
• Closer to Fine - Indigo Girls (Indigo Girls)
  
• Where the Streets Have No Name - U2 (The Joshua Tree)
• Angry - Matchbox Twenty (Mad Season)
• Never Let Me Down Again - Depeche Mode (Music for the Masses)
• Smells Like Teen Spirit - Nirvana (Nevermind)
• Lay Your Hands on Me - Bon Jovi (New Jersey)
• Radio Song - R.E.M. (Out of Time)
• Who Will Save Your Soul - Jewel (Pieces of You)
• Let's Go Crazy - Prince and The Revolution (Purple Rain)
• St Teresa - Joan Osborne (Relish)
• Damn I Wish I Was Your Lover - Sophie B. Hawkins (Tongues and Tails)
• Spiderwebs - No Doubt (Tragic Kingdom)
• Runnin' With The Devil - Van Halen (Van Halen)
• Sunday Bloody Sunday - U2 (War)
• Baba O'Riley - The Who (Who's Next)
• Breathe (2 A.M.) - Anna Nalick (Wreck of the Day)
• I'm the Only One - Melissa Etheridge (Yes I Am)
• Real World - Matchbox Twenty (You or Someone Like You)

I am sure there are more out there that I missed from my collection, especially the ones on vinyl that I don't have converted to MP3.
