Music mogul Jay Z held a press conference Monday (March 30) and officially introduced the owners of the re-launched streaming service.

During the press conference, musicians like Alicia Keys spoke on the value of TIDAL and giving artists ownership.

Alicia Keys emphasized that Tidal is the world’s first streaming platform owned by musicians. She went on to say that Tidal will deliver “exclusive experiences that will be available nowhere else.” Each artist and Tidal co-owner then signed a declaration that details their aim for the streaming service. The musicians then stood around awkwardly for a few minutes as the crowd took photos. (Business Insider)

The music superstars also took to their Twitter pages to promote the new campaign.

Various musicians, including the aforementioned, have changed their Twitter page profiles.

Madonna, Kanye West, Rihanna and Beyoncé are throwing their weight behind Jay Z’s Tidal. Ahead of an announcement later today, various big names are showing support for the Spotify-rivalling music streaming service by turning their Twitter profiles blue. Nicki Minaj, Coldplay and Usher have also joined the co-ordinated Twitter marketing campaign by tweeting the #TIDALforALL hashtag to their fans. (CNET)

Despite previously showing disinterest in music streaming service Spotify, country singer Taylor Swift‘s tunes popped up on TIDAL last week.

As of yesterday, tracks from Taylor Swift are streaming on Tidal. Aspiro services are available in dozens of countries, but has only around 500,000 total subscribers and just 17,000 on Tidal as of December 2014. There are over 15 million paid subscribers and 60 million active users on Spotify. So why does Swift want to be on Tidal and not Spotify? She is protesting the free tier on Spotify, which she says doesn’t fairly compensate artists. Tidal, by contrast, focuses on providing extremely high quality audio files and is only available to subscribers willing to pay $20 a month, double the cost of Spotify. (The Verge)
