Madonna is one of the greatest female entertainers of our time
I agree - Madonna has been very influential in music industry and pushed the envelope consistently on social issues.
She is referred to as the Queen of Pop ever since the 80s
Do you have any favorite songs of Madonna?  I really enjoyed her song with Justin Timberlake singing, "Four Minutes".  It really shows how adaptive she is in today's current environemnt.
My favorite song is Like a Virgin. I also enjoy Justin Timberlake's music as well
