Jay-Z launched a music service named Tidal last month to compete with Pandora and Spotify. It was all great for a good two weeks, then, it wasn't. From BGR:
Two weeks after Tidal briefly cracked the U.S. iPhone top 20 download chart, the app has crashed out of the top 700. Apparently American consumers have limited empathy towards Beyonce and Nicki.

As a matter of fact, something curious can be seen in Spotify's download performance right after Tidal media campaign started bashing its allegedly meager payouts. Spotify surged back into the iPad top 40 download chart on March 31st, right when Tidal's anti-Spotify invective hit its peak in American media. This had not happened since November 2014.
So Spotify is better than Tidal. Will Tay Tay rejoin it?
