My predictions and thoughts.
Chris is a front guy for a band, not a solo artist, and will end up as lead singer for someone big, I think.
Kat McPhee is a broadway show singer, as she proved with "Rainbow". She will have a tough time selling individual records. There are lots of gorgeous singers out there with her kind of talent. Anyone heard of Diana Krall? She'll make a career in music, and it won't suprise me to see her in stage shows.
Taylor Hicks is an anomoly. Simon is going to have a TOUGH time promoting him. He is a good singer, but was so successful because he is fun to WATCH, not listen to. His song isn't strong, and doesn't do justice to his voice and talents. I think a debut album covering some of the great Elvis, Joe Cocker, Ray Charles songs would be fun.
Mandisa and Paris are great, just too young still. In my mind Mandisa has the looks, style, and power to be huge, while I think Paris will be a force in the R&B market.
Pickler will get a country contract, and do OK. She could be a breakout singer if she gets some good songs early.
Elliott is talented, but his look is so normal that I think people will have a tough time marketing him.
The rest are pretty much good fish in a great big sea!
