Jay Z celebrated the 1 million user milestone for his Tidal music streaming service with a sold-out concert at Brooklyn's Barclays Center.
The performance lineup included celebrities like the hip-hop mogul's wife Beyonce, Usher and Nikki Minaj.
All of the money raised at the concert is going to charity, according to organizers.
Tickets cost between $74 and $240 on the Tidal site, but fans were able to stream the show online and donate toward the concert's chosen charities.
