It's
OK if people think it sounds like Creed as opposed to just Tremonti's sound/style and vice versa.
IMO, they are one and the same (until I hear otherwise), no matter what label you want to put on it. The perception of sound is unique to each individual listener.
Back to the topic.... I think Mark's voice sounds great on this track. I hope what he's done in the studio will translate just as well onstage.
