In an interview with Mania Club, Universal Champion Roman Reigns revealed he’s waiting for the right time to debut his new theme music:

“The music, that’s a little more than me creating my own music. We have to go through the channels with that one. It’s not like I came out and am an ultra bad guy. You’ve seen it in little steps and little layers. I want all the nuances to add up.

Because I am a full-time performer, you have to keep things fresh, so I decided to save the new music. Hopefully, down the line, once more drastic things happen and the story unfolds.”
