A couple of lyrics have meanings that you need to think a bit about, but there are some pretty clever meanings: Fireflies has 'I'd like to make myself believe that Planet Earth turns slowly'. The point is that it doesn't; life goes by too fast most of the time.
One lyric in Silhouette is 'the more I try to move on, the more I feel alone'. Doesn't this seem to remarkably sum up Adam losing fans over the development in his style in the Shooting Star EP and The Midsummer Station? Of course, it may very well also/in fact be a reference to Ann Marie.
Owl City has an odd version of this with his song "Alligator Sky". When you look around and notice there are no people and the earth is abandoned. Gives a slightly spooky feeling.
Owl City's lyrics are beautiful and full of wonder, right? Wrong. The ever jolly lyrics to "Fireflies" is actually about his struggles with depression and extreme medical insomnia. And when you listen to the lyrics, that song that used to make you wanna dance slowly becomes tragic and sad. Think about it. Seriously. Listen to the lyrics.
It's hard to say I'll rather stay awake when I'm asleep/I'm far too tired to fall asleep. Anyone with insomnia will feel the emotional burden of those words.
"I am a cold seahorse, feeling warm in your sands" (Hello Seattle) has been interpretted in a rather crude way by YouTube commenters.
