Jay Z has relaunched Tidal, the music streaming service he acquired earlier this year for an undisclosed amount. It's the first move by the music elite to leave Spotify and other freemium services.

Tidal comes with two tiers, $10 per month for normal music streaming and $20 per month for lossless music streaming. There is no free model with ads, which might entice labels and artists that find Spotify's service crippling to revenue.

A whole host of artists got on stage to sign a contract deal with Tidal, including Madonna, Kanye West, Beyonce, Jack White, Rihanna, Daft Punk, Coldplay's Chris Martin and deadmau5.

It's not clear the exact amount these artists will get, but it seems like the people on stage are getting a better deal than regular artists, who will be paid similar amounts to artists on Spotify.

To bring users onto the service, several artists will offer music a few days early on Tidal. It's not clear if this is earlier than Spotify, or exclusive to Tidal. The latter could be huge, considering iTunes, Beatport and other music services normally get exclusive coverage.

It could also hurt Beats Music, Dr. Dre and Apple's music streaming service that will relaunch in the summer. Apple might have to start battling Jay Z for exclusive contracts and in that fight Apple has $179 billion more than Jay Z to spend.
