Nope. "This Fire Burns" was all about proving yourself and making it through things and coming out on top. He has already proven himself and is currently one of the top 4 in the company.
"Cult Of Personality" is far better. Face or Heel the lyrics fit perfectly. As a Cult of Personality is a figure/role model that rises through mass propaganda, and he has been pushed as the #2 babyface for the past year, before turning heel again.
Plus, I am pretty sure he will turn face again after WrestleMania 29.
If he were ever to change it only "Miseria Cantare" would work. He used it in ROH as a heel too for a while.
But overall, he should just keep "Cult Of Personality", as he is going to be one of the top guys in the company still and of course it is a good well known song. Plus it sounds awesome.

I call dibs on GTS, Pepsi Plunge and running knee in corner. I am sure Sheamus will take the rest.
He's been a legitimate main event level talent ever since he returned with 'Cult of Personality'. There's no reason to change it at this point. It's called progression. Why have him go back to an old theme song when his career has clearly come a long way from that time period?
