Great list, but how come you haven't added Slip Inside This House by 13th Floor Elevators and Epitaph by King Crimson ? They are soo good. Also, props for having Born On The Bayou higher than Proud Mary, it's so much better.
A few off the top of my head that I would have included:
The 13th Floor Elevators - Slip Inside This House [2]
The United States of America - The Garden of Earthly Delights
Fleetwood Mac - Oh Well
Free - Walk in My Shadow
you'd think i of all people would've known sublime was a 60's band. but , while i'm no authority on 60's music whatsoever, i feel like "i'll follow the sun" could've edged out some of your beatles picks.
