As far as an underrated Beatles song, I'd say "And Your Bird Can Sing" I just love the driving guitar and full sound the song has
Also that. There's some Beatles stuff for wherever you are in your life. Which is weird for a band that only really had a 6 -8 year run, but they really ran the gamut of experiences and emotions in that time and had three such very different writers. There's music for when you're feeling content. Experimental and curious. Angry. Horny. Contemplative. Depressed. Political. Smitten. You name it, and they wrote that feeling.
"Here Comes the Sun" (personal favorite; one of my first favorite songs) "Don't Let Me Down" "A Day in the Life" "You Never Give Me Your Money" "I Am the Walrus" "Helter Skelter" "Happiness is a Warm Gun" "Get Back" "I'm Only Sleeping" "Tomorrow Never Knows"
Gonna be totally honest I think George as a Beatle gets waaaaaaaaaaaaay too much credit but Here Comes the Sun is an all-time favorite of mine, too. edit: George wrote very good songs. But George did not write many Beatles songs and only a handful are top tier Beatles songs. It is deeply upsetting to nerd me when people say George is better than Paul.
Paul was a better Beatle than George but George was a far superior solo artist than Paul. Paul's solo music and Wings stuff is truly mediocre.
Paul has a lot of great solo stuff. Harrison really lost interest in his career after a few albums. He does have easily the best Beatle solo record though.
I feel like I should declare my religious denomination in this thread: Let It Be is better Spector-ized.
- not really interested in hearing the new Sgt Pepper mix - not really interested in reading someone write about every Beatles song - "Revolution 9" ranks bottom 5 of enjoyable Beatles songs, but top 5 in most important Beatles songs - All Things Must Pass is my favorite post-Beatles solo album - John Lennon overall released my favorite post-Beatles material - Paul's New was an absolutely stunning late career album - my favorite under-apprecaited Beatles jams are I Will, Mother Nature's Son, Everybody's Got Something To Hide Except For Me And My Monkey, I'll Follow The Sun, Things We Said Today - I didn't include the entirety of Rubber Soul, Revolver or Sgt Pepper in the above list because I can't imagine any of those songs NOT being appreciated to the fullest degree
On the Let it Be thing: I definitely sympathize with the complaints about it, and why Paul in particular feels the way he does. Considering where my tastes tend to gravitate I think that, had I explored their catalog later in life, I might feel differently. But I didn't even know Naked was a thing until I did a mass exploration of their stuff in high school. So for me it's just kind of a nice curiosity--similar to one of Dylan's Bootleg records. Spector's version is the album. I have zero desire to alter it, even for "Don't Let Me Down" (probably my second favorite Beatles track, but it works just fine on its own for me).
I finished the audiobook for Paul McCartney: A Life about a week ago. It was very enjoyable, and I'd recommend it to anyone! It goes through his entire life and career
Yer Blues is one of my favorites by them. Such a low key heavy song in their catalogue. Love the lyrics: "If I ain't dead already, then you know the reason why". Which I interpret as a riddle and the answer is because he's already dead (inside).
I've seen so much discussion of their stuff that I really don't know what counts as "underappreciated," but I think "Blue Jay Way" is a beautiful, haunting song that might be my favorite Harrison track if it wasn't for "Here Comes the Sun."
"It's All too Much" is one of my favorite toss offs/rarities. It basically wrote the blueprint for Oasis' entire career too lol
There is nothing mediocre about Band on the Run or Ram. Not all of Paul's post-Beatle work is as good as the Beatles, but there is some great material as well.
I've recently had my appreciation for "I'm So Tired" and "Sexy Sadie" grow quite a bit, whereas I thought they were just solid album filler before.
