The ink on Jay Z's purchase of music-streaming service Tidal isn't quite dry, but that's not stopping the musician/entrepreneur from getting a start on things. The company announced earlier today that it would offer a non-lossless option for half the cost of its original high-definition plan -- down to $10 per month from $20. That's not all. At the official relaunch proceedings this evening, Alicia Keys revealed that a lineup of artists, including Jay Z, Kanye West, Jack White, Deadmau5, Daft Punk, Usher and many others, are all part owners in the endeavor. The goal for Tidal moving forward is to offer a music-streaming option that benefits both artists and listeners alike. With artists becoming increasingly frustrated with compensation from the likes of Spotify and others, it'll be interesting to see how Tidal keeps its musicians happy while offering an attractive slate of both regular and lossless tunes, as well as HD video and editorial content.
