Patti Smith, "Rolling In The Deep"

You know how you know you’ve written a good song? I mean, besides the fact that it spends seven weeks at the number one spot on the pop charts, and the 2.6 million albums you’ve sold because of it? And besides Billboard declaring it, “the biggest crossover song of the past 25 years?” When Patti Smith covers it in concert. And when she says she wishes she could remember the words better, but that, “I love this fuckin’ song, even though I can’t/And I’m here to testify: Adele, she’s great!” Adele must be psyched.
