“Fireflies” is the debut single from Synthpop artist Owl City’s album Ocean Eyes. Relient K vocalist Matt Thiessen is featured as a guest vocalist in the song. Thiessen described the song as “a little song about bugs and not being able to fall asleep at night,” though the fireflies in the song’s title also serve as a metaphor for the loss of childlike imagination and wonder in adulthood.
The single has attained worldwide success, topping the charts in the United States, Australia, Belgium, Denmark, Ireland, Sweden, Norway, the United Kingdom, and the Netherlands.
