When in the time we listen to songs they get older and we get tired of hearing them. We move on to listen to newer songs. It is just in our nature.
I think this method is better. Anyway, more new songs coming for us is for the benefit of us. We get to enjoy them. They become part of our lives. You begin to decide for your favorite songs.
Music is another way to get off of your depression to make it go away. You become healthy and happy. They are there to make your life positive.
