Nice avatar sublime!!
I do beg to differ with your description..you list some people who are already professionals in the industry..whether you think they are talented is another matter.
In addition to what Sublime already said, in this thing (AI) you have people who are wanna bes. A very few might be ok..or even good, but there are some real stinkers there, let me tell you! And they do all the behind the scene "drama" too, complete with toothless trailer trash relatives that tag along because Ellie Mae is just so talented (not!!) and we want to be there for her, and they have t-shirts with her name on. Then of course they show them crying and outraged when Ellie Mae gets tossed. Or you have someone who thinks he is the next Mick Jaeger, Bono or whoever, and he gets tossed and they have him raging at the camera because he is a 100x better singer than Simon and he'll show him, @#%!, dude!! (OF course, Simon isn't a singer..he's a record producer)
OK..so I've watched a few episodes of this to..I'm ashamed to admit. I'm sure PBS probably had something better on that night I should have been watching, but it's like driving by a wreck..sometimes you have to look!!!
