Lately, Winehouse had been more famous for her druggy exploits than her performances.

Anyone who saw the YouTube footage of a June concert in Belgrade knew she was ill — she cancelled her European tour immediately after. Before Saturday, that clip was a funny train wreck. Now it looks to be a cry for help.

Winehouse had only released two discs of music, her last and most famous, Back to Black, in 2006. But although her quantity was minimal, the quality was so outstanding, and revealing, that it may have been all she could give.

She lived her life like the lyrics she wrote: her misery, heartache and self-destructive urges all spoke to a pain that connected to listeners around the world.

She told us she was trouble. But we never believed her when she said she was no good.
