The Beatles - In My LifeNow, as mentioned these all mean a great deal, even though I appreciate some are very popularist choices and will potentially bring down scorn upon my cultural taste. So to get around the strict eight disc rule here are some more from the shortlist in a similar chronological order:
Wendy (was Walter, at the time) Carlos - from Switched on Bach - Brandenberg Concerto No.3 In G Major 1st Movement
Emerson, Lake and Palmer - from Pictures at an Exhibition - The Great Gate of Kiev
Queen - These Are The Days Of Our Lives
J S Bach - from the St. Matthew Passion - Wir setzen uns mit Tränen nieder
Peter Gabriel - The Power Of The Heart
Coldplay - Fix You
Sir Edward Elgar - from The Enigma Variations - Nimrod
with the Peter Gabriel track as my favourite
Easybeats - Friday On My MindAgain, even this more esoteric list leaves out many I would love to feature... oh woe!
Fleetwood Mac - I need your love so bad
The Nice - Intermezzo from the Karelia Suite
Carl Orff - from Carmina Burana - Fortune Plango Vulnera
Bob Dylan - When He Returns
Van Halen - Jump
Imogen Heap - Hide and Seek
Arcade Fire - Intervention
