I just finished my Spotify playlist of the Beatles. Listened to ever album from start to finish and picked out 112 songs of theirs that I really liked.
In terms of stylistic approach to their discography, I feel like with everything from "Help!" onwards, none of the individual albums have the specific style some of you are locking it into. There are a couple of songs on each album that have a specific style that remind you "Oh this is when they went to India", "Oh this is when they took a bunch of LSD", or "Oh this is where Lennon and McCartney started maturing and wanted to branch out into their own thing". In general though, most any song from "Help!" and on fits with any album they put out.
It's all just Beatles music for the most part, IMHO of course.
