Madonna is a 60 year old woman doing pop music.
She also didn't send songs to radios because she knows they wouldn't play her.
You need to realize Madonna is not competing with anyone in their 20's, 30's or even 40's right now. She's beyond that stage and trying to think she should even do that is ridiculous!
She's still doing better numbers than every woman pre-Beyonce. Look at Mariah, Janet, Celine's english albums usually sell around the same as Madonna. Madonna has already surpassed sales from Britney, Christina Aguilera, etc...people 2 generations younger than her (Mariah etc were the ones before).
She also just gave us 6 music videos for the first time since ever. She doesn't need to do that shit anymore lol. She clearly is doing this because she loves it. If she wanted to just do money she'd re-release all her material, promote that, announce her first Greatest Hits tour and do stadiums with it. Clearly that's not where she is at fortunately.
