Those Facebook requests.
Do those people not get that R1 isn't going to play a song just because a bunch of foreigners who don't even listen to R1 tell them to?
The anger, comments, and petitions are all pointless. R1 has chosen not to play her because people don't want to hear her (sorry, foreign madonna fans from Brazil mean nothing to R1), not her age. Look at iTunes if you want proof that people don't like the new music.
