Bruno Mars & Mark Ronson sued over Uptown Funk...again

US electro funk band Collage is suing Bruno Mars and Mark Ronson for allegedly copying parts of its song for use in their 2014 hit track Uptown Funk.

The complaint, obtained by Pitchfork, was filed against the pop duo for "deliberately and clearly" copying their 1983 single Young Girls.

Sony Music Entertainment, Warner/Chappell Music, Atlantic Records, RCA Records and others are listed alongside Mars and Ronson in the lawsuit.

The 1980s Minneapolis funk band claims Uptown Funk is "an obvious, strikingly and/or substantially similar copy" of their song.

They listed "the distinct funky specifically noted and timed consistent guitar riffs present throughout the compositions".

And the "virtually if not identical bass notes and sequence, rhythm, structure, crescendo of horns and synthesizers" as the main violations.

This is the second time Mars and Ronson have been accused of copyright infringement over the song.

In May, funk group The Gap Band got 17% of all publishing royalties and writing credits for giving up sections of their 1979 hit Oops Upside Your Head.

A third group called The Sequence have also alleged the duo copied their song, but have yet to file a complaint.

Collage is seeking damages and profits from Mars, Ronson and other producers involved.

The complaint was filed by the only living member of Collage, Larry White, and the estates of two others.

Representatives for Ronson and Mars have not yet commented on the allegations.
