It's like as if Rihanna released You Da One as the lead, instead of 2nd single.
A great, passable song, but not what one expects for the lead single, indeed.
Madonna is likely comfortable with all her achievements, and felt that she didn't need to risk it, I think, but if she did take risk, I'm sure it would have paid off.
Also, have you witnessed the nonesense of Gaga's hyper-stans, well a faction anyhow, that have taken to paying people to slander Madonna?
As fan of both such actions appall and disgust me.
