I am going with the American albums, cuz that is what I grew up on. While I love "Abbey Road" and the white album (properly known as "The Beatles"), to me, what makes the Beatles, the Beatles is the earlier stuff. I love that "middle period"..."Help", "Rubber Soul", "Revolver"....but my favorite was/is "Beatles '65" It had songs like "I'm A Loser", "No Reply", "Baby's In Black"...just a little more adult than "She Loves You" and "I Want to Hold Your Hand"...but not as trippy as they would get. Just perfect pop albums for me. If you are a little younger, and only know the cd's, you grew up with the British releases..."Beatles '65", "Beatles VI" and "Help" would be covered by the British versions of "Help!", and "Beatles For Sale".
"Beatles VI" holds a special place for me, because it is the first record I ever purchased, with my own money. Every record I had before that was a handme-down, or a gift...but I heard the song "Eight Days a Week" and I just had to have it...spent my own snow shoveling money down at AM&A's on "Beatles VI". Soon discovered gems like "You Like Me Too Much" and, my now, personal favorite, "I Don't Want to Spoil the Party"
