Following public criticism from the likes of Lily Allen and Mumford & Sons, Jay Z's Tidal is back in the news, after it was announced that Tidal CEO Andy Chen was stepping down. Now Jay Z and co-owner Jack White are personally calling subscribers for the world's first artist-owned music streaming service to say thank you. 

Business Insider recently spoke to Tidal's chief investment officer Vani Schlogel, who said: "[Jay Z] called some of his fans and one of them made the funniest comment. He said: 'This is the best customer service call I have ever received'." Schlogel also revealed that the artists who signed up to Tidal have special accounts, which enable them to see who is listening to their music, and gives them the option to see subscriber's contact information so that they can get in touch with them directly.

Tidal recently addressed Allen's and Mumford and Son's criticism that the platform will set emerging artists back, adding a new feature for rising talents.
