About Fire Flies

"Fireflies" is the debut single from American electronica project Owl City's album Ocean Eyes. Frontman Adam Young wrote and produced the track, with Matt Thiessen also producing and providing guest vocals. Young described the song as "a little song about bugs and not being able to fall asleep at night." The song is built around a "bleepy" synthline and includes lyrics about insomnia, fireflies and summer.

The song topped the Billboard Hot 100 for two non-consecutive weeks. Outside of the United States, the song also topped the charts in Australia, Belgium, Denmark, Finland, the Netherlands, Norway, the Republic of Ireland, Sweden, and the United Kingdom. "Fireflies" was Owl City's only top 40 hit on Billboard Hot 100 until three years later when "Good Time", a duet with Canadian singer Carly Rae Jepsen, peaked at No. 8 on the chart. It has been covered by Christina Grimmie, Cheryl Cole and others. "Fireflies" is featured in the video game Disney Sing It: Party Hits, and was used in the promotional video for EyePet. It is available as downloadable content for Guitar Hero 5, Guitar Hero: Warriors of Rock and Rock Band 3.
