Musically talented or otherwise does not negate the fact that she, and others before her, were just junkies. Every human has a talent of some description that sets them apart whether its admired by the wider public or not and whether that person ever gets the chance to realise that talent and make something of it. Talent is not unique or an excuse!
She had that chance and made very little of it. Worse than that she's perpetuated the notion that drug / alcohol abuse is part of the acceptable rock and roll lifestyle to many a youngster. Hopefully her death will serve as a good example of why not to follow that lifestyle.
