Beyoncé brought two fans on stage to dance to 'Single Ladies,' and they killed it

MIAMI — Beyoncé's "Single Ladies" dance is not for the faint of heart. Just ask Justin Timberlake, Andy Samberg and Bobby Moynihan.  

But when Beyoncé brought out two fans for the I Am... Sasha Fierce lead single during the kickoff of her Formation Tour Wednesday night in Miami, well, they schooled just about everyone. 

The moment made the girls party that was the Formation Tour that much better. Beyoncé stood to the back as the two did their thing, occasionally providing encouragement. 

This wasn't the only time that fans took center stage. At one point, Beyonce played a couple fan's videos of their reactions to her surprise release of "Formation."

Spotify says Tidal's 'Lemonade' exclusive is bad for everyone

While Beyonce's Lemonade will be available for download on iTunes tonight, it won't be available to stream anywhere but Tidal for the foreseeable future.

And Spotify isn't happy about that. 

In a statement to Mashable on Sunday, Jonathan Prince, global head of communications and public policy at Spotify, slammed Tidal, saying long-term exclusives aren't good for anyone.

"We believe long-term exclusives are bad for artists and they’re bad for fans," said Prince in an emailed statement. "Artists want as many fans as possible to hear their music, and fans want to hear the music they’re excited about - exclusives get in the way of both. Of course, we understand that short promotional exclusives are common, we don’t have a total policy against them, and we certainly respect the choice of artists to decide what’s right for them."

On Saturday, shortly after Lemonade was released on Tidal during the visual album'sgroundbreaking premiere on HBO, an industry insider told Mashable that the album would be available to stream exclusively on Tidal "in perpetuity." Representatives for Beyonce have not responded to a request for comment from Mashable.

Beyonce isn't the first one to have her album available exclusively on one platform. Last year, the late Prince — notoriously anti-Internet — pulled all of his music from streaming services except for Tidal. Taylor Swift's 1989 is only available on Apple Music. Adele, meanwhile, didn't allow her latest album, 25, to be streamed anywhere at all. 

Kanye West said The Life of Pablo would always be a Tidal exclusive, but the album was released to other streaming services about six weeks later. And fans weren't happy about it, ashe and Jay Z were sued by a fan for "fraudulently inducing consumers to subscribe to Tidal."

The Life of Pablo was streamed on Tidal 250 million times in its first 10 days alone, and likely was a big factor in the streaming service's boost in subscribers. Mashable has not yet received information on Lemonade's streams so far.

Prince added: "Bottom line, we’re looking forward to sharing Beyonce’s awesome new music with her millions of Spotify fans as soon as we can."

Representatives for Soundcloud Go and Google Play have not responded to Mashable's request for comment. A representative for Apple declined to comment on the Tidal exclusivity.
