Some of the WWE Superstars that have been with the company for years have different versions of their theme music which is often remixed over and over like The Big Show, Chris Jericho, The Rock, The Undertaker, Kane and Stone Cold changed his a lot in the past but he doesn't anymore. Others kept the same song for a long time like Mick Foley, John Cena, Shawn Michaels, Triple H, Vince McMahon, Shane McMahon, Brock Lesnar, Randy Orton, Edge, Kurt Angle, Mickie James and many others.
