10. We were genuinely surprised to find legendary singer Linda Ronstadt among the top-ten best sellers. It's not that we don't think she's great – we do! – but Ronstadt's not nearly as bold-faced as Babs and Britney. While younger generations may not appreciate Ronstadt, we'll always have a place in our heart for this lovely lady, particularly her 1975 chart-topper, "You're No Good." Click here for the video.
