I don't know, i love his theme, it's unique. Changing themes can be a risk and it may not work out, look at Barrett's.
It could be an interesting development, how about suggestions for the style he should go with?
Also look at how calling him the GOAT has affected this thread, it's caused people to go off tangent and not focus on discussing the topic. I know you're only saying it for the lulz, but it's becoming counter-productive at this point.
Dwayne Johnson/JBL/MVP/Ric Flair/Steve Austin doesn’t need their theme music changed. Well maybe Dwayne’s cause his current one is kind of generic compared to his past ones but besides 4/5 of the guys are not on the current roster anymore anyway.
