Twitter users have pointed out the similarities between the opening bars of the boyband's new single 'Live While We're Young' and the punk band's 'Should I Stay or Should I Go?'.
"Wow blatant copy of The Clash's Should I Stay Or Should I Go intro in One Direction's new song, RIDICULOUS (sic)," one user posted.
Another tweeted: "Am I the only one that can hear The Clash in the first 10secs of One Direction's new song?"
One Direction were forced to release the video to their new track early after it was leaked online.
The song will be available to download from September 30, with their second album Take Me Home following on November 12.
The boyband recently invited Robbie Williams to join them "any time" after he admitted he was "jealous" of their success.
