Whenever I think about movies I always look at that art process as having the best of a lot of worlds. Because if you watch a great film you have a musical element to it not just on the scoring but in the way that the shots are edited - that has music and rhythm and time.
I don't think you get to good writing unless you expose yourself and your feelings. Deep songs don't come from the surface they come from the deep down. The poetry and the songs that you are suppose to write I believe are in your heart.
