I'm sure you and I could come up with a hundred songs that are worse than
anything the Beatles, Stones, or Who recorded. I personally don't see how
any Beatles song could be on a list of the 50 worst songs of all time. "Helter Skelter" is a good hard-rocking tune with an interesting triple fade-out, and the immortal refrain at the end, "I've got blisters on my fingers" that segues beautifully into George's "Long Long Long." Even something like "You Know My Name (Look Up the Number)" is fun to listen to and sing along with, and is nowhere as stupid or annoying as anything put out by most of the MTV generation.
Heck, I'd rather listen to Their Satanic Majesty's Request straight than anything put out by Britney Spears or Justin Timberlake!
