Hmmm...favorites or level of importance?
From an importance standpoint, I would say:
1. Eleanor Rigby (a rock song with no guitar, bass, keyboard or drums? Preposterous!)
2. Hey Jude (a rock band can't have a hit song over 7 minutes long, it just isn't done!)
3. Norwegian Wood (the first time a sitar appears on a rock release -- the Yardbirds used one, but on a demo)
4. Tomorrow Never Knows (one of the most influential pieces of psychedelia ever recorded)
5. Yesterday (the most covered song in history -- so that must mean something, right?)
6. A Day in the Life (Progressive before there was such a thing)
7. In My Life (Lennon's final piece of evolution from pop tune writer to rock composer)
8. I am the Walrus (psychedelic symphonic orchestration? And lines from King Lear?)
9. Something (the first Harrison song to appear on the A side of a single)
10. Helter Skelter (Paul McCartney writes an acid rock song? And Charles Manson hears voices)
