I am not sure what metamorphosis Lauryn went through but it really has done a number on her.

She fell off. Regardless of what anyone has to say she is FAR from her best vocally. Rapping or singing. Her tone has become to husky. Regardless of how it has been she like Whitney Houston did not protect their chords. Serious damage was done.

There are many singers before/after whose voices have withstood time so that cannot be an excuse.

She needs to revamp her style.
Her voice needs help. I can still hear traces of it underneath all that huskiness though.
It seems her life of breeding a tribe did a # on her.
And why does she appear so off? Is she losing her marbles?
