Newbee, you are da man! That's a great list for neophytes and I agree with it 100%. If one were to stray either side of the Romantic period I would be forced to add these as my next ten choices:
1. "Concierto de Aranjuez" - Rodrigo
2. "Piano Concerto, Opus 20" - Scriabin
3. "Rhapsody in Blue" - and other Gershwin works
4. the Gilbert & Sullivan highlights CD on Telarc
5. "Mass in B-Minor" and bunches of others - Bach
6. "Rite of Spring" and "The Firebird" - Stravinsky
7. "Concerti Grossi," "The Messiah," and more - Handel
8. Symphonies - William Boyce
9. "West Side Story" and "Candide" - Bernstein
10. "Madama Butterfly" (opera) - Puccini
Don't forget the last three symphonies by Mozart (oops! that's eleven!)
