Lyrics of I don't know why

I don't know why the sky is so blue?
I don't know why i'm so in love with you?
If there were no music, i would not get through
I don't know why i know these things? but i do

I don't know why somewhere dreams come true?
I don't know where we'll find a place for you?
Every time you look that way i lay down my life for you
I don't know why i know these things? but i do

I don't know why sun can make you cry?
I don't know how i'm bound to get you back? but i'll try
They don't mean to cause you pain, they're just afraid of loving you
I don't know why i know these things? but i do

I don't know why the trees can grow so tall?
I don't know why i don't know anything at all?
If there were no music, i would not get through
I don't know why i know these things? but i do, i do
I don't know why i know these things? but i do
