On 30 March 2015, it was announced that Rihanna is a co-owner, with various other music artists, in the music streaming service Tidal. The service specialises in lossless audio and high definition music videos. Jay-Z acquired the parent company of Tidal, Aspiro, in the first quarter of 2015. Including Beyoncé and Jay-Z, sixteen artist stakeholders (such as Kanye West, Beyoncé, Madonna, Chris Martin, Nicki Minaj and more) co-own Tidal, with the majority owning a 3% equity stake. "The challenge is to get everyone to respect music again, to recognize its value", stated Jay-Z on the release of Tidal.
