I want to know the answer to the following question:
Beyonce joined 2 other women on what list from Billboard magazine in 2011?
All the background I'm provided with is that "In May 2011, Billboard magazine listed Beyoncé at number 17 on their list of the "Top 20 Hot 100 Songwriters", for having co-written eight singles that hit number one on the Billboard Hot 100 chart.". Is that enough to answer the question?
