When The Shield parted ways in June 2014, it was imperative that each of the members established their own identity as singles competitors. Dean Ambrose started wearing wife beaters and leather jackets, Seth Rollins sported Power Ranger-like attire, and Roman Reigns continued to enter through the crowd to the old Shield entrance music. Okay, so Reigns isn't too different from when he was with The Shield, but Ambrose and Rollins are entirely new competitors. Ambrose in particular found his footing right from the get-go as a babyface when no one expected him to given he's such a natural heel. Despite that, he got over with the audience in no time, partly due to the new awesome entrance music he received. It's fairly generic and repetitive when you first hear it, but the more you listen to it, the more it grows on you. The revving of the engine at the start of the song never fails to fire up the WWE Universe when his music hits an arena. It's in line with his character seeing as he's always ready for a fight every time he makes his entrance.
