There's been some truly awful and inappropriate cover songs throughout modern musical history, but there's one in particular which really grates on rock fans.
A poll by Rolling Stone chose Miley Cyrus and her cover of Nirvana's 'Smells Like Teen Spirit' as the worst cover of all time. Miley was slammed by Nirvana fans for attempting the song on a tour in April.
Speaking about Nirvana as an introduction to the performance, Miley said: "Without them, I wouldn't be here. They're the ones who gave me the strength and courage to do this, and I hope that I can be that person for you guys. More than anything else in the world I want you guys to follow your dreams, because it's the only way to make life worth living, I promise you that."
The album 'Nevermind' was released one year before Miley was born.
She proceeds to butcher the song with her country drawl like a broken auto-tune unit, and tries headbanging and jumping to fit in with the song. But props to the band, who can certainly play with attitude - Miley can certainly afford good musicians.
