Christopher Loudon of Jazz Times noted in 2004, Ronstadt is "Blessed with arguably the most sterling set of pipes of her generation ... rarest of rarities – a chameleon who can blend into any background yet remain boldly distinctive ... It's an exceptional gift; one shared by few others." In total, she has released over 30 studio albums and 15 compilation or greatest hits albums. Ronstadt charted 38 Billboard Hot 100 singles, with 21 reaching the top 40, 10 in the top 10, three at number 2, and "You're No Good" at number 1. This success did not translate to the UK, with only her single "Blue Bayou" reaching the UK Top 40. Her duet with Aaron Neville, "Don't Know Much", peaked at number 2 in December 1989. In addition, she has charted 36 albums, 10 top-10 albums and three number 1 albums on the Billboard Pop Album Chart. In a 2011 interview with the Arizona Daily Star she said, "I am 100 percent retired and I'm not doing anything any more". It was announced publicly in August 2013 that Ronstadt had been diagnosed with Parkinson's disease in December 2012, which left her unable to sing. Her autobiography, Simple Dreams: A Musical Memoir, was released in September 2013. It debuted in the Top 10 on The New York Times Best Sellers List.
