What you just listened to, assuming you made it from start to finish, is the new rap song from Miami-based artist YNIQ (via MMA Hot Sauce), who is giving props to Ultimate Fighting Championship (UFC) women's bantamweight titleholder Ronda Rousey.
It may not be Beyonce, but hey, at least he shouts her name a bunch of times.
It's not unusual for mixed martial arts (MMA) fighters to have their own music. Top heavyweight contender Andrei Arlovski has a track from Freddy Madball & Jaysaun that he's used a couple of times during his various walkouts (hear it).
