It is quite sad that some (if not most) are fans for the wrong reasons, Owl city is NOT aimed at 13 year old girls :P, his music is broad ranging from faith, nostalgia and awkwardness.
He is a devout Christian, and a great role model for many as he stands firm in his beliefs despite the rather pressuring modern music industry. His lyrics are cryptic (often people don't have the brain power to understand them :P, and consider them nonsensical). Overall he is an amazing talented artist, and to those who think otherwise...
GO LISTEN TO LADY GAGA, KATY PERRY, CHRIS BROWN, JASON ARMADILLO :) OR SOME OTHER IMMORAL CREEPS :p
(boy... that felt good)
Dear God, I was terribly lost
When the galaxies crossed
And the sun went dark.
But dear God, You're the only North Star
I would follow this far.
This shows his belief in Christianity
(this is just one of the many things he includes in his works)
