When iTunes used Fireflies as their single of the week. Fireflies isn't even their best song.
If you mean the most popular song by Owl City, it would be Fireflies.
If your talking about Fireflies by Owl City (Adam Young), it is very popular.
I believe Owl City started late 2006 - early 2007, but Adam wasn't entirely popular until the song "Fireflies" came out some time in June 2009. :) ~Tiffany
This question is a matter of opinion, but the two most popular Owl City songs are 'Fireflies' and 'Good Time' featuring Carly Rae Jepsen. If you want to decide your favorite song, that isn't neccesarily the most popular, feel free to acquire a list of Owl City songs and decide for yourself. After all, only you know what you like best. I hope this helps!
