I dont think whitney will ever return to her former glory, this isnt just a mariah/michael style bad patch, this is a complete physical and mental breakdown, she's totally lost it.

Her music is brilliant tho, her greatest hits album shows that she has had an amazing career filled with great songs and she is a great vocalist.

Unfortunately people like Mariah Carey have surpassed her in every way, mariah is the better singer, she is the better artist, mariah writes her own stuff, her albums have an artistic vision (whether u like it or not) and she has developed from her debut through Music Box to Daydream/Butterfly to Rainbow/Glitter and i think the Emancipation of Mimi is sort of like a round up of all the stuff she has done in the past.

But again its all down to personal preferences, some people like Hero others The greatest love of all, some people like We belong together others my love is your love. personally i like em both, but mariah tops whitney every time.
