My take on it. I did also really like mer. She is talented. I have seen many other artists who come into their fold. They are given a taste of real success and fame and then, give them a bit of time before requiring them to sell their souls.
Most seem to do so. A few, I have really liked, do not.
Those that do not fade from view but still make a living in their field. They have loyal followings. They also have piece of mind and their souls.
It's very sad to me, that EVIL controls so much in the world.
Madonna probably had a year or a bit more before she turned.
