Tidal: Will Jay Z's new streaming service sink or swim?

From left: Usher, Rihanna, Nicki Minaj, Madonna, Deadmau5, Kanye West, Jay Z and J. Cole onstage at the Tidal launch event on March 30. Over the last few days, Jay has made good on his vow to bring fans music from top stars that they can't get anywhere but his uber-hyped, new streaming service, Tidal. Jay started at home, with the release on Saturday of a new song/video from wife Beyonce, "Die With You."
