I have to say that while the mainstream D.A.R.E Brainwashed society may think she's a trainwreck, at least she's staying true to what great music's always been about. Without drugs, we'd still be listening to big band era music, and while I can occasionally dig that scene, the keyword there was occasionally.
So far as I'm concerned, I hope she gets clean when she wants to get clean, and her personal life is of no concern to the fans so long as the music continues to be good.
