Made of Machines

I'm a Walmart brand of man You can buy one and get one free Why do you put up with all my shit When I'm not who you want me to be? There's an artery in my heart That you pull at until it bleeds To reassure you I'm not made of machines Make me do what I'm just not built for I'm bound to let you down Try to make me the king of your world Yet you're wearing the crown After everything you call me I'm not a person, I'm a thing I'm just your friend that's made of machines Sit me down in front of keys I'm bound to play wrong notes But give me a little practice And I'll write stuff you can quote You may be onto something But I'm not sure if I can be How can I be famous if I'm made of machines?
