This song from Avicii, has a beautiful letter, worth reading and listening!

Hey Brother 

Hey brother, there's an endless road to rediscover
Hey sister, know the water's sweet
But blood is thicker
Oh, if the sky comes falling down, for you
There's nothing in this world I wouldn't do

Hey brother, do you still believe in one another?
Hey sister, do you still believe in love I wonder?
Oh, if the sky comes falling down, for you
there's nothing in this world I wouldn't do

What if I'm far from home?
Oh brother I will hear you call
What if I lose it all?
Oh sister I will help you out!
Oh, if the sky comes falling down, for you
There's nothing in this world I wouldn't do

Hey brother, there's an endless road to rediscover
Hey sister, do you still believe in love I wonder?
Oh, if the sky comes falling down, for you
there's nothing in this world I wouldn't do

What if I'm far from home?
Oh brother I will hear you call
What if I lose it all?
Oh sister I will help you out!
Oh, if the sky comes falling down, for you
there's nothing in this world I wouldn't do
