Cover art for Heartbeat Slowing Down lyrics by All-American Rejects, The

I love the usage of the phrase "I can feel your heartbeat slowing down" to indicate a relationship burning out--the words make me think of the beginning of a relationship, when you're with someone and you're heart's beating out of your chest from the excitement and love. Whenever I hear this song, the imagery comes to mind of love igniting and burning in the form of fast heartbeats and then love fading away, your "heartbeat slowing down."
