How much more successful was The Outfield's song Your Love because of the lyric that "You know I like my girls a little bit older"? What about Estelle's song American Boy due to the lyric "I just met a 5'7" guy who's just my type"? We will never know because we cannot run the counterfactual, but I expect that the answer is a lot. My advice to artists is to champion causes that others have disregarded. One obvious example is to go after social conservatives, which will probably separate you from 95% of your peers.
