Stuck in the middle

I spread my angel wings
And start to fly
To the heavens I sing my song
But half way through my journey I
Get stuck half in dark half in light
One wing goes black the other stays white
My halo stays but there's also a horn on my head
I grow a red tail and everyone can see
I'm stuck in the middle
Nor angel nor devil
Just half and half day light I fear night I love
Where do I belong?
I don't really know
