UNDATED (AP) -- "American Idol" chat rooms were buzzing over a controversy surrounding Chris Daughtry's version of "I Walk the Line."

Judges praised Daughtry for making the song his own when he sang it on the last episode. But some fans said the version was not his own, but ripped off from a version done by the band Live in 2001.

One fan posted a message saying "I just want to punch him in his bald head."

Another message read "This guy is a rip off. Judges are plain dumb."

And a third message read "Live singer Ed Kowalczyk called and said that he would like his vocal style" back.
