Seems most of us don't rank Sgt. Pepper as highly as music critics do. I'm in the same boat - don't think it's even in my top five of Beatles records. That said, I can understand why it's ranked highly on critics' lists based on how groundbreaking it was, and I do have some favorites:
A Day in the Life - This is not just a masterpiece to be admired, but a highly enjoyable listen. I am endlessly fascinated by it no matter how many times I've heard it. I'll write a lot more about all of these, but particularly this one, when I do my Beatles song countdown soon.
Lovely Rita - I've only recently come to appreciate this one but find it charming and hilarious. There's a point just over a minute in where Paul yells "Rita!" and then it goes into a piano part that's jaunty and fun. I assume that's George Martin on the piano, but I bet
@Godsbrother knows. Love the ending to this song, too.
Sgt. Pepper's Lonely Hearts Club Band - Love the vocal and the fuzzy guitar, but the drums really stand out to me on this.
Lucy in the Sky with Diamonds - Another that I've only appreciated more recently. The dreamy quality and dreamy lyrics, the tempo changes...
With a Little Help from My Friends - My favorite song with Ringo on vocal. The call-and-response is fantastic. I love Ringo's voice (and of course of course his drumming), but don't love his songwriting, so it's fitting that my favorite "Ringo song" isn't a Ringo song.
Good Morning Good Morning - This song is bonkers and I love it. No idea how Ringo could perform this song. He's off the chain on this one.
Within You Without You - I could listen to this forever. It's very soothing. Love its placement on the record and how it breaks up the two circus-y songs.
