The likes of Jay Z, Beyonce, Madonna and Nicki Minaj have launched their very own streaming service called Tidal. The A-listers are co-owners of the new music platform alongside the likes of Rihanna, Kanye West and Daft Punk. Tidal originally launched last October, but was recently bought by Jay Z, who hopes to encourage artists and labels to give Tidal new music a week in advance of other services.
