Madonna has been my favorite entertainer since I was seven! 
Oh, yes.  I love Madonna, but she was popular when I was a little older than you.  I was a teenager.  What is your favorite Madonna song?
La Isla Bonita if I have to pick just one. I can't believe she is 59! 
La Isla Bonita is a great song.  I remember when that came out in 1986 as I was a senior in high school.  It came from her "True Blue" album.  
Papa Don't Preach is from that album. I remember how edgy it seemed to me. 
Yes, it was a little controversial for it's time if you think about it.  It took topics like abortion and teen pregnancy on.  
Very ahead and brave in my young mind. I didn't realize you could question adults. 
She definitely was brave with her music, but the controversy worked for her.  But, critics loved her music regardless of the controversial topics.
