Task: Question Answering
Input (English): Passage: Wyatt Frame, an executive with the pop music record label MegaRecords, is confronted on a private jet by boy band DuJour over a strange backing track they discovered on their recent single. Wyatt and the plane's pilot parachute out of the jet, leaving it to crash and "kill" the band. 
Wyatt lands outside of the town of Riverdale, and begins searching for a band to replace DuJour. He discovers struggling local rock band The Pussycats: lead vocalist and guitarist Josie McCoy, drummer Melody Valentine, and bassist Valerie Brown. The group accept Wyatt's immediate offer of a major record deal despite its seeming implausibility, and are flown to New York City with their manager Alexander, his sister Alexandra, and Josie's friend Alan M. The group is rebranded "Josie and the Pussycats", to Valerie's chagrin.
Meanwhile, MegaRecords CEO Fiona meets with world government representatives. She details how the United States government has conspired with the music industry to add subliminal messages as backing tracks to pop music to brainwash teenagers into buying consumer products. The government theorizes that the economy can be stimulated by channeling the disposable income of young people into trendy and expensive goods; music artists who discover the truth are "killed".
The band's first single is released, and due to subliminal messaging, is an instant success. Valerie begins to resent the attention the label gives Josie, while Melody's uncanny behavioral perception makes her suspicious of Fiona. Fiona orders Wyatt to kill Valerie and Melody before they uncover the conspiracy; they are sent to a fake appearance on Total Request Live where Carson Daly attempts to kill them, though they survive due to his incompetence. 
Question: Who discovered a strange backing track on their recent single?
Output (English): DuJour.
