Jay-Z’s set to fully announce the debut of his newly
acquired music streaming service, Tidal, today at 5
P.M. Eastern time. The buzz began last night as various
musical celebs from Kanye West to Madonna changed

campaign entitled #TIDALForALL. The service comes
with a $9.99 price tag for premium membership and
a monthly tag of $19.99 known as ‘hi-fi’. More info
