Really, really rich people have problems, too.

At least, that appears to be Beyoncé’s explanation for the infamous elevator brawl between her husband, Jay Z, and sister, Solange, that took place back in May after the Met Gala in New York City. The R&B superstar fired back about the incident via a remix of her song “Flawless” (featuring Nicki Minaj), which was released online with absolutely no warning late Saturday night. (You can listen to the song here.)

“Of course sometimes [expletive] goes down when there’s a billion dollars on an elevator,” Beyoncé says on the track. Then she says it again, louder. And in case we didn’t get it the first time, there’s a cash register “ka-ching!” sound in the background, illustrating the massive amounts of money between the elevator-riding trio.

Obviously, Twitter lit up with people obsessively analyzing the line — as well as the rest of the song, which is Beyoncé‘s first collaboration with Minaj.

The original “Flawless,” famous for incorporating Chimamanda Ngozi Adichie’s “We Should All Be Feminists” Ted Talk, was originally a track on Beyoncé‘s self-titled album that she dropped in a similar fashion late last year: Randomly, late at night, with zero promotion beforehand. It proved to be a dynamite way to get publicity and appears to be working again.

Curiously, the song also brings the brawl back into the headlines. The notoriously private family released a statement to the Associated Press after the fight footage went viral on TMZ (“[Jay Z and Solange] both have apologized to each other and we have moved forward as a united family”), and the matter seemed closed.

Later, Solange seemed to confirm that in a Lucky magazine story, playing down the incident: “What we had to say collectively was in the statement that we put out, and we all feel at peace with that.” Well, apparently, Beyoncé had a bit more to say.

It’s also worth noting that this remix comes on the heels of rumors heating up about the demise of Beyoncé and Jay Z’s marriage, as well as disappointing ticket sales for their “On the Run” tour. There’s been no comment on the former, and strong denials about the latter.
