The DJ duo are not in the producer's good books

Mark Ronson has hit out at The Chainsmokers after they dissed Lady Gaga’s track, ‘Perfect Illusion’.

During an interview with Rolling Stone, Alex Pall, one half of the group, said Gaga’s comeback single “sucks”.

His bandmate Andrew Taggart then added more positively: “She’s a great artist – like, Jeff Koons made a sculpture of her…”

“I agree,” Pall replied. “And a lot of talented people worked on that song. But…”

Ronson tweeted to the duo yesterday (October 29), saying: “Back to being the charisma-bypassed champions of 2 bar Ableton loops? Well, smash it while it lasts, fellas!!”

He added a link to an article on low-risk investments by way of a P.S, as Consequence Of Sound reports.

Gaga herself responded to the pair earlier this month when she tweeted her new song ‘A- YO’ at them. “maybe u guys’ll like this 1 better,” she wrote.

Meanwhile, Ronson and collaborator Bruno Mars are being sued for copyright infringement over their song ‘Uptown Funk’.

Funk band Collage, who were mainly active in the early ’80s, claim elements of ‘Uptown Funk’ are “deliberately and clearly copied” from their 1983 single ‘Young Girls’.

Their complaint, obtained by Pitchfork, says: “Upon information and belief, many of the main instrumental attributes and themes of ‘Uptown Funk’ are deliberately and clearly copied from ‘Young Girls’, including, but not limited to, the distinct funky specifically noted and timed consistent guitar riffs present throughout the compositions, virtually if not identical bass notes and sequence, rhythm, structure, crescendo of horns and synthesizers rendering the compositions almost indistinguishable if played over each other and strikingly similar if played in consecutively.”

This is not the first time the origins of ‘Uptown Funk’ have been called into question. All-female rap group Sequence claimed in February that elements of ‘Uptown Funk’ are stolen from their song ‘Funk You Up’, though they have yet to file a lawsuit.

Ronson and Mars previously added five new writers to the song’s credits in order to avoid a ‘Blurred Lines’-style lawsuit. That case ended with Pharrell Williams and Robin Thicke having to pay Marvin Gaye’s family for the likeness between Gaye’s 1977 song ‘Got To Give It Up’ and their 2013 chart-topper.

Three of the newly-credited ‘Uptown Funk’ writers were members of The Gap Band, who claimed there are similarities between ‘Uptown Funk’ and their own hit ‘Oops, Up Side Your Head’ last year.
