Bruno Mars and Mark Ronson are being sued by 70s rap group over 'Uptown Funk'

A female rap trio, called The Sequence, have alleged that Mars and Ronson stole parts of their 1979 track for 'Uptown Funk'.

According to TMZ, they're arguing that Uptown Funk has “significant and substantially similar compositional elements' of Funk You Up”. The trio have requested a jury trial and financial restitution over the issue.

The Sequence are considered one of the pioneers of old school hip hop, after being the first female rap team signed to the Sugar Hill label.

This isn’t the first time Bruno Mars and Mark Ronson have found themselves in trouble over the hit single.

In September, a suit was filed by Lastrada Entertainment Company, Ltd., the music publishing house that holds the copyright to Zapp's 1980 song 'More Bounce to the Ounce'.

They claimed in court that: “Mark Ronson failed in his goal to write something new. Substantial parts of 'Uptown Funk' were copied from 'More Bounce to the Ounce’.”
