Post Malone has insisted a songwriter who is suing him over 'Circles' had nothing "original" to add to the 2019 hit.

The 26-year-old star, his producer Frank Dukes, and Universal Music Group were sued by Tyler Armes in April 2020, who was seeking royalties and other money owed from the track, as well as asking for co-writer and co-producer credits on the song, and on the same day, the 'Rockstar' hitmaker filed a lawsuit of his own to ask a judge to rule the man had no claim to the song's copyright and was not involved in writing it.

And now, in a new court filing, Post - whose real name is Austin Post - insisted Tyler didn't contribute anything "original" to the song, just “an admittedly extremely commonplace guitar chord progression,” and potentially a “fragment of a guitar melody that Armes claims he sung to Post”.

New court documents obtained by Rolling Stone magazine read: “Armes admitted that his contributions did not even rise to the level of originality, which is also required in addition to the fixation requirement. He either conceded that his ideas were commonplace musical devices or failed to meet his burden to demonstrate any originality otherwise. Armes thus cannot even establish the threshold requirement that he made a copyrightable contribution.

“Armes does not have a shred of affirmative evidence with which to meet his burden of proof that his alleged contribution to the guitar melody is original.”

Post is asking for Tyler's lawsuit to be dismissed and for the judge to conclude the writer is "not a joint author" of the track.

A lawyer acting on behalf of Tyler - who claimed he was initially offered five per cent of the song's royalties but that was removed entirely when he tried to negotiate a larger share - accused Post of making a "desperate" bid to avoid a trial.

Allison Hart said: “We believe that the motion for summary judgment is a desperate attempt by Post Malone and Frank Dukes to try to avoid a trial in this action. We are confident that we will prevail in defeating the motion and look forward to going before a jury.”
