Hogan was ahead of his time in entrance music, but that was thanks to Vince McMahon and WWE's music composer Jim Johnston. They pioneered the use of licensed songs as entrance music, and Hogan was the first wrestler in both the WWF and WCW to use licensed music on a regular basis. The nWo failed in WWE because the fans dictated that they wanted to see Hogan become the old Hulk Hogan instead of the nWo's Hollywood Hogan. Hogan was the main draw of the nWo, and when the decision was made for him to turn face, the writers didn't know what to do with the rest of the group. Kevin Nash became the defacto leader and they decided to bring back Shawn Michaels as the on-screen leader, but Nash got hurt soon thereafter and Scott Hall was fired after being late to an event (presumably due to drinking). Without the star power of Hogan, Nash, or Hall, the nWo was a shell of its former self and there was no point in continuing the angle. No one would've taken an nWo group seriously with Big Show, X-Pac, and Booker T with Shawn Michaels as strictly a manager. This was prior to HBK making an unexpected in-ring return from injury.
