The effect of the typicality of song lyrics on song popularity: A natural language processing analysis of the British top singles chart

This study investigates the relationship between the lexical typicality of song lyrics and song popularity in the UK Official Singles Chart from 1999 to 2013. Drawing on natural language processing (NLP) techniques, we develop a multidimensional measure of lyrics’ typicality that captures lexical repetition, complexity, thematic content, and emotional tone, addressing methodological limitations in previous research that relied heavily on static word dictionaries. By analysing 1,457 songs that reached the top five chart positions, we demonstrate that lyrics’ typicality significantly predicts the duration a song remains in the top five but does not affect the peak chart position or the trajectory of popularity (skewness and kurtosis). Our findings suggest that while typical lyrics may contribute to a song’s longevity within a given canon, they do not necessarily guarantee chart-topping success. This research contributes a replicable, dictionary-free methodology for assessing lyrics’ typicality and offers insights into the nuanced role of lyrics in shaping musical preferences.
