Several artists who pulled music from Spotify are showing up on TIDAL, a new music streaming site expected to relaunch this week. Jason Aldean is one country star to appear in a 32-second-long promo for the service.

The clip shows over a dozen A-listers converging for some sort of secret meeting. Beyonce, Rihanna, Madonna and Usher are a few of the others that make cameos. TIDAL is owned by rapper Jay Z, and the service is said to promise HD video quality, high-fidelity sound and a curated content experience.

It’s a direct competitor to Spotify, the streaming service Aldean, Taylor Swift and several others (Brantley Gilbert, Justin Moore) pulled their music from in 2014. Aldean encourages his followers on Twitter to make their profile pics blue, as he’s done.

“Together we can make history,” he writes before using the #TIDALforALL hashtag.

TechCrunch speculates that TIDAL is offering artists better terms of service (meaning, more money) than other streaming sites. However, there are far few monthly subscribers on TIDAL. The tech website says there are just 35K, compared to over 15 million paying subscribers on Spotify. Currently, TIDAL costs twice as much, although it’s possible that could change with today’s 5PM ET press conference.

Other stars in the TIDAL commercial are Kanye West, Chris Martin, Jack White, Nicki Minaj and Daft Punk. "Change your avi in support of what is fair, of what is the future. The tides have changed, Barbz. Love u #TIDALforALL,” Minaj writes on Instagram.

It’s not clear if the mass exodus from Spotify was related to TIDAL, or if Gilbert or Moore will be joining the movement.
