This discussion seems to me to reflect the shifting relative importance of songwriting and production. If you watched the Weekend's Superbowl halftime show, I think you can see just how important the skill of production has become. There is nothing special about his music as far as melody is concerned and the lyrics are not brilliant, but the package obviously works. It doesn't do anything for me because I like to be moved by music but many, many people love it. So this seems to demonstrate that you can take a bland song and gussy it up with skillful production techniques and achieve a marketable product. I'm not sure that works in reverse. These days in mainstream pop, it's all about the production.

Of course, if you start with a good song to begin with then you can end up with something far better.
