Wrong, wrong, wrong.
While I'm not a huge Chris fan, I could certainly see myself sitting down and listening to his album when it comes out. On the other hand, I can't for the life of me imaging being able to sit through 12 songs in a row of Adam screeching into the microphone. He's got a good voice but somewhere in every single song his shrillness drives me nuts. If I heard him on the radio I would likely change the station.
If he could control himself (this is apparently a problem in many aspects of his life) he would be a great singer, but he sounds like he's crying hysterically at some point in every song. Sorry, but that's not for me.
That sounds just like my grandparents who never understood Elvis, his talent or his appeal.
