Is "Uptown Funk" a rip-off of the 1980 disco classic "More Bounce to the Ounce"? That's what a company called Lastrada Entertainment claims.
They own the rights to "More Bounce", which was released by the funk group ZAPP . . . and they're suing Sony, Spotify, Apple, and songwriter (slash) producer MARK RONSON. They're NOT suing BRUNO MARS.
They want everyone to stop playing and selling "Uptown Funk" . . . and of course they want unspecified damages, too.
