Another Great Song Ruined

Here we go again.  First it was Fergie when she ripped apart Guns N Roses, "Sweet Child O Mine" at the Super Bowl.  And now we have Miley botching up Nirvana's "Smells Like Teen Spirit".  I don't think either of them understand that if you must sing a cover of a classic rock song, you mustn't fuck them up royally. Perhaps they should just not sing them in the first place.
