The tune is an updated version of Shout, the unofficial anthem of the England team during the 2010 FIFA World Cup, reported Daily Express.
"Just heard the new updated version of DizzeeRascal (sic) and JKCorden's (sic) Shout - Incredible! Hopefully first radio play this weekend," Cowell posted on Twitter.
