2. 'Smells Like Teen Spirit'
"Smells Like Teen Spirit" was the song that broke Nirvana and ushered in a new era of music. "I was trying to write the ultimate pop song," Cobain told Rolling Stone in 1993. "I was basically trying to rip off the Pixies . . . It was such a clichéd riff. It was so close to a Boston riff or 'Louie, Louie.'" Cobain quickly grew weary of his creation. "It's almost an embarrassment to play it," he said. "Everyone has focused on that song so much. The reason it gets a big reaction is people have seen it on MTV a million times. It's been pounded into their brains . . . I can barely, especially on a bad night, get through 'Teen Spirit.' I literally want to throw my guitar down and walk away."
