Firefly envelops the listener in lush lyrical imagery woven into a soothing acoustic instrumental with synths & piano adding a dreamy feel. The song starts by recalling summertime as a child & the joy of trapping fireflies in grandma’s backyard, “We trapped that magic in a jar, just like we had our very own stars.”  The song crescendos after missteps of adulthood are revealed that led to a feeling of being trapped just like all of those fireflies. It ends with musical & lyrical resolution & hope.
