Nirvana’s 'Smells Like Teen Spirit' is credited with bringing grunge to the mainstream and ending the era of 1980s hair metal. The song's title came from a funny misunderstanding. Kathleen Hanna, the lead singer of Bikini Kill, spray-painted 'Kurt Smells Like Teen Spirit' on Kurt Cobain's bedroom wall. Cobain thought it was a profound, revolutionary slogan about his rebellious spirit. In reality, Hanna was making fun of him because he smelled like 'Teen Spirit,' a brand of deodorant his then-girlfriend Tobi Vail used. Cobain didn't find out about the deodorant brand until months after the song was released. The track became a global anthem for Generation X, reaching number six on the Billboard Hot 100. Its 'loud-quiet-loud' dynamic structure became the blueprint for 1990s alternative rock, influenced heavily by the Pixies.
