Several studies show that a concept or object is more popular when it is easier to process. The present research applies this notion of processing fluency to the lyrics of all 271 top 5 songs on the United Kingdom chart for each week from 1999 to 2014. The processing fluency of the lyrics was computer scored for readability, presence of rhyme, and complexity, and popularity was assessed in terms of peak chart position and duration of tenure on the chart. After controlling for the energy of the musical component of the song, analyses showed that factors relating to the processing fluency of the lyrics predicted peak popularity but not duration of chart tenure. Significant relationships were observed between peak popularity and both rhyme saturation and basic lyric readability properties.
