to a pop song, i.e,. people can easily remember the song and make it popular. I think the melody is the THE most important thing in a song, which you may not agree. Other stuff like harmony, 半音，假声，and 枴来拐去like Jay Chou, David Tao, and Lihom Lee can only 增色，but not the soul of the song. I agree with you that it is time to make it simpler instead of making it more complex. If you let Mr. Zhao hear the song you wrote for your father, I believe he will have a totally different opinion. That song is a soul song. That song's range is very large, but it does not matter because it really carries out what you think in a simple and direct way which can touch people's soul directly. Keep up you good work. That was my own opinion and may be wrong.
