Music like Fireflies

"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. Internationally, the song also topped the charts in Australia, Belgium, Denmark, Finland, the Netherlands, Norway, Ireland, Sweden and the United Kingdom. "Fireflies" was Owl City's only top forty hit in the United States until three years later when "Good Time", a duet with Canadian singer Carly Rae Jepsen, charted at No. 8. It has been covered by Christina Grimmie, Cheryl Cole and others.
