Who sings the song id rather be awake when im asleep?

the song is "Fireflies" by Owl City/Adam Young.


"You would not believe your eyes
if ten million fireflies
lit up the world as I fell asleep.

'Cause they fill the open air
and leave teardrops everywhere.
You'd think me rude but I
would just stand and stare.

I'd like to make myself believe
that planet Earth turns slowly.
It's hard to say that I'd rather stay awake when I'm sleep,
'cause everything is never as it seems."...
