Remember when Jay Z said Tidal, the streaming music service he acquired earlier this year, was doing just fine? Well, as it turns out, things are still on a respectable course. The musician/entrepreneur took to Twitter to reveal a significant milestone for Tidal: 1 million subscribers. "'Nothing real can be threatened, nothing unreal exists,'" Jay Z tweeted. "Tidal is platinum." To celebrate, Tidal announced it will be hosting a charity concert in Brooklyn's Barclays Center on October 20th, featuring high-caliber artists such as Beyonce, Nicki Minaj, Prince and, of course, Jay Z himself. And don't worry if you can't attend, the service says it plans to stream it to everyone (including non-subscribers) on its website.
