"Hearts On Fire" is a song by the Swedish metal band HammerFall, released in 2002. The lyrics speak of a group of people who are shunned by society and oppressed by a ruling class. Despite this, they continue to hold onto their beliefs and fight for freedom. The "writings on the wall" refer to the signs that the ruling class's time is coming to an end, and the oppressed people are ready to rise up. The "heathens" are the rulers who have used their power to keep the people down. The chorus, "Hearts on fire, burning with desire," embodies the passion and determination of the oppressed people. They are ready to fight for their freedom, even if it means sacrificing themselves. The song also references the Templars, a historical order of knights who fought for Christian causes during the Crusades. The band sees them as symbolizing the fight for freedom and justice. Overall, "Hearts On Fire" is a song of rebellion and perseverance. Its message of standing up to oppression and fighting for what you believe in is a universal theme that can resonate with anyone struggling against injustice.
