Well because nobody fucking understands me because I'm so individual, unique and intellectual that I have to let the world know. It's my gift to the world and it would be a crime to keep my awesomeness to myself.
Like most pop songs you hear every day... all inspired by my work bro.
Music-making is my only solid skill and it helps keep my brain active and alive. I get some satisfaction from listening to my tunes when they are done well. It's also nice knowing that they are exclusively mine. But I make them free downloads anyhow.
