As of now, the joint Sprint x Tidal site serves as a landing page touting Sprint's six-month complimentary Tidal subscription.

Earlier this month, Tidal and Sprint detailed their partnership after the NBA Finals debut of a 4:44 trailer starring Lupita Nyong’o, Danny Glover, and Mahershala Ali. "More than two-thirds of mobile subscribers stream music an average of 45 minutes per day, making our partnership with TIDAL a natural fit for Sprint and our commitment to offering innovative, affordable and worry-free service," Sprint CEO Marcelo Claure said in a press release.

Jay's most recent studio album was Magna Carta Holy Grail, released way back in 2013.

Roc Nation artist Vic Mensa was pressed about the meaning of 4:44 in a recent interview with Real 92.3. Mensa, understandably, kept his answers vague. "It's an important number," Mensa said. "It's symbolic. It means things and people will find out . . . I actually don't know any types of timelines or anything." Asked whether Jay had played him any new music, Mensa said he "might have heard some."
