Our kids are in a little band, and they like to play video games, and my wife and I do our best to live a low-key, non-Hollywood kind of life.
Melodies can be good depending on the context. You can have a simple melody, and if the harmony behind it is interesting, it can make a very simple melody really different. You can also have a complex melody. The more complex it is, the harder it is to sing, and then sometimes it can sound contrived. You could write a melody that would be fine on a saxophone but if you give it to a singer, it can sound raunchy.
