jay z launches spotify rival tidal

American rapper Jay-Z is really trying hard to keep his not-so-successful music streaming service Tidal alive. Recently, the rap mogul announced his plans to unearth songs he never performed before or hasn’t performed in a long, long time for an exclusive concert.

The concert, titled “Tidal X: Jay Z B-Sides”, will be held in New York on 13 May 2015 and is only meant for Tidal subscribers, who can submit a playlist on the service to win tickets, or just watch the show live on Tidal.com.

This seems to be an initiative taken by Jay-Z to keep his service going and convince his Tidal subscribers to stay, considering that Tidal is much more expensive compared to other cheaper and free services.
Previously, Jay-Z posted a series of long rant on his Twitter page in order to defend his Tidal service:
