Aspiring artist Luis Adrian Cortes Ramos, a former finalist on TV talent show Idol Puerto Rico, sued Martin in 2014, claiming he submitted his version of the track as part of SuperSong, a contest Martin and Sony Music executives launched in 2013 to find a new tune for the FIFA World Cup championships in Brazil.

According to court documents, the competition organisers promised "the winning composer would be recognised and he would be given credit for his work" - but Ramos insisted that never happened. He also alleged his single failed to make the official cut for the final five in the SuperSong contest, but was subsequently released by Martin, without his knowledge or permission.

Ramos' initial lawsuit was reportedly dismissed, but now he has filed new documents seeking $10 million (GBP7 million) for distress, copyright violation, and "severe mental anguish" he claims he has suffered and "continues to suffer" for loss of his composition and creation "without being credited or compensated".
