Earlier today, Tidal, the music streaming service that Jay-Z purchased earlier this year, broadcast a live “launch” of its product. I say “launch” because really nothing was announced, despite the hype. The company trotted out big names in music including Daft Punk, Madonna, Nicki Minaj, Kanye West, Chris Martin of Coldplay and more, to make a declaration that they as artists, are uniting against other streaming services and give the power back to them.
