Abbey Road, though, like you, I could go 5 different ways depending on the day I'm asked.
The 2nd side of Abbey Road is brilliant. The medley, drum solo and trio of dueling guitars works so well. Love the "Her Majesty" Easter egg. "And in the end, the love you take is equal to the love you make," is the greatest final line of a band's final album, ever. ( and yes, Abbey Road is the final album even though the Phil Specter- ruined Let It Be was released last).
Side one features George's twin masterpieces, "Here Comes the Sun" and "Something," which Frank Sinatra called, " One of the greatest love songs of the 20th Century." Is there a better opening tune than "Come Together," on any album ever?
Also, "She's So Heavy" is a great rocker with one of Paul's great bass lines.
Add in an iconic album cover and a slew of "Paul is Dead" clues and, yeah, it gets my vote. Of course, maybe tomorrow I'll make the case for The White Album.
