If you're seeing blue on Twitter and Facebook, you're not alone.
Many of the world's biggest artists are rallying behind Jay Z's new music streaming service Tidal by changing their profile and cover photos to teal blue on Sunday night.
Jay Z plans to unveil Tidal's artist-friendly game plan on Monday at New York City's James A. Farley Post Office at 5 p.m. ET. Tidal will compete with platforms like Spotify as well as Apple's nearly ready and revamped music service involving Beats Music.
Among the artists supporting Jay Z's new venture are his wife Beyoncé, Kanye West, Rihanna, Madonna, Coldplay, Usher, Nicki Minaj and more heavyweights.
Earlier this year, Jay Z bought Aspiro, a Swedish tech company that runs two streaming music services (WiMP and Tidal) for $56 million. Monday's announcement will finally reveal what the 45-year-old rap mogul will do with his purchase.
Tidal's website  describes the service and pricing as such: "Introducing the first music streaming service that combines the best High Fidelity sound quality, High Definition music videos and expertly Curated Editorial."
