I would argue that if a majority of an audience says something is good (subjective to them), then that thing is good objectively. If something is popular, then it is good. Not to say it is without flaws. That is different.
Take the example of spelling that another user brought up. They claimed it is objective, but that isn't really true. Is the correct spelling color or colour? The answer to that is cultural, and therefore subjective. Unless you hold as I do that popularity is similar enough to objectivity to qualify. The cultural or popular notion determine what is right regarding subjectively judged subjects. This notion, including the spelling and even usage of words, can change over time.
