Answer:
Bringing more edge to their songs and comments by John Lennon
Explanation:
"Day Tripper" was a 1965 single in which some magazines thinking track is written about a prostitute. "Rubber Soul" was a pot inspired album, "Revolver" was an LSD inspired album. Press also thought track 2 of "Rubber Soul" was about a lesbian. Tracks like Tomorrow Never Knows and I Want to Tell You had an obvious drug influence. Tracks like "I'm Only Sleeping" and "Tomorrow Never Knows" having the first songs that featured anything that played backwards, tape loops, and studio effects. Even before Revolver, "Paperback Writer" uses an innovative rock riff and a very innovative echo at the end of a verse. It's B-Side "Rain" was the first song to feature backwards vocal. Before Revolver, John Lennon made an infamous comment saying "We're bigger than Jesus", which sparked controversy in America, with Radio Stations hosting Beatle burnings and such things. "Sgt. Pepper's Lonely Hearts Club Band" was another album inspired by Acid, with "A Day in the Life" and "Lucy In The Sky With Diamonds" being banned from radio play. "Magical Mystery Tour" had "I Am the Walrus" banned from airplay, and once again, every song off Mystery Tour was in some way inspired by Acid.
<em>"The BEATLES" </em>otherwise known as the "White Album" introduced a new genre; Heavy Metal. "Yer Blues" having lyric like "I'm lonely, wanna die", "Piggies" being about Police, "Back in the U.S.S.R" being written during the Cold War era, "Happiness is a Warm Gun" well that one explains itself, "Why Don't We Do It In the Road?" being literally what it sounds like, yet only using minimal instruments.
"Yellow Submarine" having "Only a Northern Song", an attack on their signed label named Northern Songs Ltd. Also, Side 2 had George Martin's film score, Tracks 1 and 6 are repeats, so fans were buying a full new album for only 4 songs
"Abbey Road" having a song about a kid killing people, "I Want You (She's So Heavy)" being a start of Doom Metal, and the excellent Medley on Side Two
"Let it Be" was recorded before Abbey Road, there is controversy on which album should be first.
In many ways, the Beatles are very controversial, but always the best.
