making a song vs a "hot 16"

Though a lot may beg to differ there is a significant difference between a song and just a quick 16 bars to a beat. When writing a song it takes patience and brainstorming to make sure your concept is well interpreted and delivered. A song should have a message behind it and leave your audience with a piece of you as an artist. There is also a personal aspect to writing a song, it usually has a great deal of attachment to a significant part of your life.
