Blessing or Curse?

Music is life it's heart is the drum
Experience is the melody, hear my song hum
But not over the sound of hearing my engine run
It growls and grumbles like im carrying a ton
I just want to move the world and shine like the sun
While living like a guide similar to Gods son
I can't predict my future I accept whatever comes
I expect good funds but only problems come
So i'm packing heat for my safety
Conscious of demons I weild my pen on a daily
Sharper than a sword I use mine to strike a chord
First it was just to score
In heat or when i'm bored
But the fling became more
In my chest is where it's stored
Protected from the enemy, caged my ribs horde
All the things I love and all the things I loved
Everything I prize and all I have to hide
Far from the public eye, with you I spend my thoughts
Rocking where eyes are lost, lies my heart
Deep within notes only to be felt and heard through the contact of waves with nerves
Music is the purpose that my life serves
Im on a one track state of mind,trains don't swerve
Rarely do they reverse
So I train and reherse
Life is made of music your story is the verse
What is your soul worth; a blessing or curse?
