Can't Understand lyrics

You don't understand me.
You don't know who I am.
I don't care what you may call me
But I only need my heart,to guide me.

I lookin' for the path to hormony.
One day you'll see everything I am.
I don't know,
I don't care you don't care,
You don't understand
But mostly you can't understand me.

And you can'tttttttt understand meee,eeeeeeee,meeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee,eeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee,
