Jay-Z’s Tidal streaming service will be supported by damn near every artist he’s ever posed for a photo with.

Jay-Z recently acquired HiFi music streaming service Tidal. Today he is beginning a new campaign for the service featuring tons of his friends, including artists like Kanye West, Rihanna, Madonna, Nicki Minaj, Daft Punk, and of course his wife, Beyonce. Many musicians are supporting Tidal, changing their social network profile photos to the blue color that represents Jay-Z‘s wavy take on music streaming.

Today at 5 PM EST, Hov and co. will also live stream for Tidal and we’ll find out what the ad above is all about. Nobody knows what exactly will happen during the stream, but let’s hope we get some new music out of it.

UPDATE: No new music came from the Tidal live stream, but we did get to see a video of every artist involved talk about the product, which costs $20 per month. A ton a of popular artists also took to the stage. After Alicia Keys did some talking, the artists signed a declaration of their own…and that was it.
