UFC is currently in a bit of a rut as far as champions go. While the titleholders in each division are incredibly skilled mixed martial artists, with the exception of Jon Jones and Ronda Rousey they're all rather bland. And with the two mentioned, they've apparently both embraced their role as villains, relishing the fans' rejection. Ronda is still incredibly popular and her fights do very good numbers on pay-per-view, but her showings in interviews and especially her stint coaching The Ultimate Fighter have soured the public on Ronda Rousey: the person. Rousey: the fighter, is still an absolute monster. So of course Ronda extends her IDGAF attitude to her walkout music. When the sounds of "Bad Reputation" by Joan Jett blare through the speakers, fans know the nastiest woman in MMA is on her way down to armbar the sh*t out of some unlucky lady. It's hard to imagine a more fitting anthem.
