In January 2018, it was announced that Piçarra would participate in Festival da Canção 2018, singing a song that he composed, called "Canção do Fim". This was his first attempt at this competition, which allows the winner to participate in Eurovision Song Contest 2018 in Lisbon. Days before the Grand Final of Festival da Canção 2018, and after winning the second semi-final with the maximum score, he decided to leave the competition, due to accusations that he had plagiarised "Open Your Eyes", a 1976 song performed by the Maranatha Singers.
