Here is another accomplishment which I think some people are forgetting about
:
4 Minutes is Madonna's first single in 6 years to get some good airplay in the US since Die Another Day in 2002. If you guys remember, Madonna was boycotted on US radio due to the American Life controversy in 2003. Up until now, Madonna was basically shunned on radio. Without the help of Justin and Timbaland, 4 Minutes would have most likely been ignored on radio just like the songs that came before it. They both helped Madonna get airplay again after 6 years. At one point, it was the 5th most played song in the US, and it peaked at #11 on the Hot 100 airplay chart. I'm honestly glad I was able to hear the Queen on US radio again!
I can't think of her worst but it's probably "Jump" or "What It Feels Like for a Girl".
