They're more or less the same song, according to Weezer frontman Rivers Cuomo � although he didn't realise that when he was writing his version. He tells Rolling Stone: "It was the first Weezer song I wrote, back in 1991. I was trying to write a Velvet Underground type song because I was super into them, and I came up with the guitar riff. I picked up the guitar and the first thing I played was that riff.

"It just feels so classic to me. Even now when the band starts to play it, it takes over the energy in the room and you're transported into the world of Weezer. It wasn't until years after I wrote it that I realised it's almost a complete rip-off of Sanitarium by Metallica." - But guess what? The Metallica song itself was inspired by another hit
