Season 2

Season 2 will begin on 11/18. iTunes has the season 1 & 2 soundtrack and looking at it, these songs will be season 2:

Sgt. Peppers Lonely Hearts Club Band
Hey Bulldog
And Your Bird Can Sing
Drive My Car
I'm Happy Just To Dance With You
Elinor Rigby
I'll Follow The Sun
Across The Universe
Yellow Submarine

I'm guessing there's going to be more as this only covers about 5 episodes(2 songs per episode). Again more of an emphasis on '66-'70. I'm Happy To Dance With You is from 1964(Hard Days Night), I'll Follow The Sun from 1964(Beatles for Sale), and Drive My Car is from 1965(Rubber Soul) but the rest are from '66-'70.
