WJ didn't perform at the WMA because he can't sing at all anymore. That is the real reason he hasn't toured for a decade, along with his bankruptcy. Even his vocals on "We've Had Enough" four years ago were poor and he never had a strong voice to begin with, certainly not comparable with the real King, Elvis Presley. Jackson has had financial problems since at least 1998 due to his declining sales and popularity, as well as his inactivity and having to support an entire family - not just those three children who aren't his biologically. In 2002 it was revealed he was in debt to various international banks to the tune of tens of millions of dollars, and after losing those lawsuits in May 2003 he was confirmed as on the verge of bankuptcy with debts of $400 million. Invincible was a flop because it sold less than a third of his last album, "Dangerous", and it was all crap. 99% of Jackson's few remaining fans regard it as his worst album. In 1989 Jackson made it known he had to be addressed as the King of Pop - meaningless, self-proclaimed title. He even planned to buy Graceland so he could demolish it, which certainly says far more about Jackson's megalomania than it does about Presley. Half the songs on the Dangerous album were crap, especially the unbelievably awful Heal the World, and it only sold 30 million copies on the strength of his previous three albums. Blood on the Dance Floor sold an incredibly low 6 million and it was rubbish. Yeah, WJ was unique all right, as many unfortunates found out. You must know some very sad 20-year-olds if they still admire that disgusting pervert. Anyway, most people know him as Wacko Jacko. Justin is the real King of Pop and like Eminem he just doesn't want to risk offending WJ's mentally ill fans. Justin will continue to perform, while Jackson's career finished a decade ago. ( )
