You may not have heard of them, but Owl City hit No. 1 on the Billboard Hot 100 this week with their ultracatchy pop number, "Fireflies." Anyone who's ever heard that song realizes that it follows the very specific pattern of blippy-emo-pop success that was set by the Postal Service on their 2003 smash LP, Give Up, yet Owl City mastermind Adam Young claims that there's little resemblance between the two outfits. "I had some friends in high school that would have it playing in their cars and stuff. It was cool, but it never really caught my ear," he tells Entertainment Weekly. "It’s funny, because the more I hear people relating the two, the more I realize that they are pretty similar — even though that wasn’t my initial goal or anything." Hmmm, wonder how Ben Gibbard and Jimmy Tamborello would respond to that? [Music Mix/EW]
