Owl City - Fireflies (Video clip)

"Fireflies" is the debut single from American electronica project Owl City's album Ocean Eyes. Relient K vocalist Matt Thiessen is featured as a guest vocalist on the song. Adam 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.

Fireflies was used in the promotional video for Sony's EyePet video game. It is also featured in Disney Sing It: Party Hits.[5] It is also a downloadable content for both Guitar Hero 5 and Rock Band 3.
