Controversy

G:son and Henrik Sethsson's song for the Eurovision Song Contest 2001, "Listen to Your Heartbeat", was accused of plagiarism from Belgium's 1996 entry "Liefde is een kaartspel". The songwriters denied the accusation, but after the Belgian songwriters and the author's organisation SABAM pressed for legal action, a cash settlement was agreed.
