Jay-Z, Madonna and other artists launch music service Tidal
Some of the biggest names in entertainment have re-launched the music subscription service Tidal, which they are billing as the first artist-owned platform for music and video. At an event in New York on Monday, Madonna, Beyonce, Kanye West, and 13 other performers announced they had become co-owners of Tidal. The service launched last October, but was recently bought by rapper Jay Z. It is hoping to compete with the likes of Spotify, Deezer and Google Play.
