Madonna and Mary J Blige are set to take different sides in a new court battle over pop hit 'Holiday'. Bosses of the publishing company behind the 1983 classic claim Blige's 'Barbershop 2 song 'Not Today' is a rip-off of the tune and they're suing the R&B superstar and collaborators Eve and Dr Dre to prove it. New York musicologist Judith Finnell has been drafted in, and she insists the Maverick publishers have a strong case. She tells American legal show Celebrity Justice, "It sounds similar enough to bear further consideration. Both the pitches and the rhythms sound closely related." (wenn)
