Jay-Z's music streaming service Tidal launched with a ton of A-list co-signs from Kanye West, Daft Punk and Rihanna. Despite the star-studded launch in March, the company has faced a slew of public relation and technological problems since its inception. However, the company's very famous co-owner Madonna brought up the subject in a new interview. Speaking on the service, the singer defended Tidal, talking about the company's core mission and hinting at upcoming changes. Madonna told the Associated Press, "It?s just the beginning, so we?re working out a lot of kinks and hopefully we?re going to build something unique and amazing that?s going to attract a lot of people."
