It is so hard to pick just one -- both categories! Honestly, because I have to do research to drill down into "least favorite..." There is a radio station near me that does Brunch With the Beatles on Sundays, so a nonstop hour of Beatles once a week. Everything's Got Something to Hide, Except for Me and My Monkey does ZERO for me. And Octopus' Garden (like Yellow Submarine) is really too repetitive and simplistic for me now. Slash annoying. Slash people are like "it's really about sex giggle giggle." That said, I loved it in high school...hmm... Like goobster, I have to admit some of my favorite Beatles songs are actually favorites due to Across the Universe covers. For instance, this song never hit home until I saw/heard it in the movie, and then it became something I loved. Bests are hard. So many are so good! I Want You (She's So Heavy) effin slaps. What a bop, am I right? Sorry. I love using the young kid terms for non-young kids music. ;)
