If you were among the 16.9 million people who watched the Grammys on Sunday, you might reasonably surmise that sisters, as Annie Lennox and Aretha Franklin so memorably put it, are doing it for themselves. The broadcast and the headlines were dominated by women, spanning several generations, from Joni Mitchell to Tracy Chapman, and from Miley Cyrus to 2-year-old Hazel Monet.

Oh yeah, and Taylor Swift.
