4. "Undone - The Sweater Song"
The initial idea for "The Sweater Song" came to Rivers Cuomo in an English class when the instructor shared an analogy favored by Albert Einstein. "I heard the analogy of the unraveling sweater," Cuomo said. "Dr. Eisenstein used the image to demonstrate the effectiveness of focused thesis statement in an essay. 'All I have to do is hold a single thread in your sweater and it will unravel as you walk away.'" Cuomo took the idea and wrote a song about a man that was unraveling like a sweater. Years later, Cuomo realized he inadvertently borrowed a bit from a Metallica tune when writing the song. "I was trying to write a Velvet Underground-type song because I was super into them, and I came up with that guitar riff," Cuomo said in 2009. "It wasn't until years after I wrote it that I realized it's almost a complete rip-off of 'Sanitarium' by Metallica. It just perfectly encapsulates Weezer to me — you're trying to be cool like Velvet Underground, but your metal roots just pump through unconsciously."
