It was recently announced that TVXQ will be joining Park Hyo Shin, SNSD's Taeyeon, Jang Jae In and Brown Eyed Soul for the OST of �'Athena: The Goddess of War.' In contrast to the soft, melancholic sounds of Taeyeon's 'I Love You' and Brown Eyed Soul's 'Put It Back', TVXQ's OST track will deliver a song characterized by a faster pulse and 'realistic sounds'. TVXQ's track will be played during the action scenes; the producers aim to use their powerful vocals as a catalyst for pumping up the viewers' adrenaline during the highly dramatic moments.
