These artists all were at the event today and signed their commitment on-stage by signing a declaration. 

The streaming service is described as a “platform owned by artists” and has a goal “to re-establish the value of music.” Keys explained on the behalf of the group, “We want to create a better service and experience for fans and artists. Our mission goes beyond commerce and technology.”

The video following the event had footage from a summit recently where the owners of TIDAL to talk about their vision. Daft Punk talked about the summit as “the Avengers of Music.”

It was previously reported that TIDAL offers two different subscription offers: $19.99 for a month of high-fidelity audio and $9.99 for standard audio. TIDAL could be streamed on the web, and downloaded with iOS and Android devices.
