Did Dream Theater Steal From Christian Rock Band?

A fan has highlighted similarities between a Dream Theater song and a Christian rock band - and former drummer Mike Portnoy agrees.
The opening song on Dream Theater's latest album "A Dramatic Turn Of Events" apparently sounds remarkably similar to a song by the band Red. The fan posted their observation on Dream Theater's forums, where other fans appear to be disappointed with the similarities.

Mike Portnoy decided to join with the discussion, taking an obvious jab at his former band mates: "Check out the first song on [John Petrucci's] fave album of the year... WOW, the arrangement and orchestration sounds awfully familiar! Surely it must be an intentional 'nugget' for the fans... It couldn't possibly be blatant formula plagiarism, now could it... ? I just have to laugh... [sic]"
When some fans took a dislike to Portnoy's tactless contribution to the discussion, he replied again: "Hey... I'm not trying to start a war... And I am indeed totally in a happy place in my life and career... I'm just merely making an observation and posting openly on my own forum like I always have and always will... If anybody ELSE wants to blow this up, it's their choice and doing... Not mine! [sic]"
It is not the first time Dream Theater have been accused of plagiarism. This year, some fans noted the similarities between their newest album and their 1992 release "Images And Words", suggesting they had even copied themselves in a bid to release new music.
John Petrucci later told Ultimate Guitar that he appreciates fans analyzing their music, but the similarities were down to the band having such a definitive style of their own.
"We really like music," Petrucci said. "We have a certain thing that we try to accomplish musically, a certain sound that makes us who we are. The core elements of Dream Theater, of who we are and how we make music. Those are elements that are identifiable. That's what gives the band its sound, and keeps the band having an identity."
