You talk about a band with some serious musical range. Check out some of the divergent genres they experimented with (with varying degrees of success) on the White Album:
SOFT LOVE BALLADS: I Will, Julia. The latter was John's loving tribute to his deceased mother.
HEAVY METAL: Helter Skelter. John had long maintained that their "Ticket to Ride" was the first Heavy Metal song.
PSYCHEDELIC ROCK: Glass Onion. By the time of the White Album, the Beatles had pretty much gone through their psychedelic phase. Were they poking fun at themselves?
COUNTRY/WESTERN: Rocky Raccoon, Don't Pass Me By. Were these parodies or tributes?
BLUES: Yer Blues. They tried.
ACOUSTIC FOLK: Mother Nature's Son. Simple and sweet.
SATIRE / SOCIAL COMMENTARY: Back in the USSR, Piggies, Blackbird. Sometimes they used the sledgehammer, sometimes the stiletto. Message delivered either way.
1920's DANCE HALL: Honey Pie, Martha My Dear. In America it was known as Vaudeville. Paul tried to recapture that sound and did a pretty good job of it I think. "Martha" was Paul's pet sheepdog.
1950's ROOTS: Birthday. A piano-pounding homage to the 1950's Black American rock that the Beatles cut their teeth on.
EXPERIMENTAL AVANT- GARDE: Revolution #9, Wild Honey Pie. Hey, they were the Beatles, and could do whatever they wanted.
and last but not least, A FREAKIN' LULLABYE! Good Night. Ringo on vocals, some studio backup singers, and a 26 piece orchestra. Perfect.
That was only half the songs on the double album!
We have not seen the likes of the Beatles for over 50 years, and may never again.
