In reply to Jake.

I don't know about Mariah, but you're sadly mistaken about Cher and Janet. They both have worldwide diehard fans too. Cher's Dressed To Kill World Tour is one of the biggest tours of the year, and Janet's Number Ones Tour sold out all its international dates, 80% of them arenas, without having released any new music in over 3 years at the time. Madonna is not the only older icon that's still beloved around the world.
