If I've interpreted this correctly,
@Neutrinos is asking for an artist's ten most well-known and/or most influential songs, regardless of our personal feelings. (For example, I dislike "Run to the Hills", but it's hard to argue that it isn't one Iron Maiden's top ten most enduring songs). Here are some picks for bands that haven't been mentioned:
The Who
- My Generation
- I Can See For Miles
- Pinball Wizard
- Baba O'Riley
- Behind Blue Eyes
- Won't Get Fooled Again
- The Real Me
- 5:15
- Love Reign O'er Me
- Who Are You
Black Sabbath
- Black Sabbath
- N.I.B.
- War Pigs
- Paranoid
- Iron Man
- Sweet Leaf
- Into the Void
- Supernaut
- Snowblind
- Sabbath Bloody Sabbath
(Comments: I considered the Dio era, but I don't think any of those songs have as much widespread recognition as the classics from the first five or six albums).
Judas Priest
- Hell Bent for Leather
- Breaking the Law
- Living After Midnight
- Electric Eye
- You've Got Another Thing Comin'
- Painkiller
- Victim of Changes
- Beyond The Realms of Death
- Heading Out to the Highway
- Turbo Lover
(Comments: the first six, I think, are set in stone. It was tough to settle on the final four. I considered some of the post-1990 material but I don't think anything was close to making the list).
Iron Maiden
- The Number of the Beast
- Run to the Hills
- Hallowed Be Thy Name
- The Trooper
- Aces High
- 2 Minutes To Midnight
- Wasted Years
- Fear of the Dark
- The Evil That Men Do
- The Wicker Man
(Comments: I'm confident that there's a broad consensus for the first eight songs listed. Arguably one of the last two spots should have gone to a Paul Di'Anno era song, but it's hard to determine which song would be the "definitive" choice from the first two albums).
King Crimson
- 21st Century Schizoid Man
- Epitaph
- The Court of the Crimson King
- Larks' Tongues in Aspic, Pt. 1
- Larks' Tongues in Aspic, Pt. 2
- Fracture
- Red
- Starless
- Elephant Talk
- Sleepless
(Comments: I'm not certain about the final choice, but the other nine are solid).
Nirvana
- About A Girl
- Smells Like Teen Spirit
- In Bloom
- Come As You Are
- Lithium
- Aneurysm
- Heart-Shaped Box
- Rape Me
- All Apologies
- Where Did You Sleep Last Night?
