Background Across the United States, the incidence of adolescent depression and suicide cases has risen in the past 10 years. Despite the risk factors and causes being multifactorial, the influence of popular culture on society and adolescents in this media-driven generation cannot be mitigated. Although the impact of social media and its effect on shaping self-identity in adolescents have been observed, the impact of music and its potential for subliminal negative messages to adolescents remains unclear. Objective This study analyzes the lyrics and music videos of the most popular music of multiple genres to quantify the frequencies of varying music theme trends. Methods The frequencies of themes of 1052 total American and Latin songs were collected from the Nielsen Music and Billboard’s top 100 chart performance from 1998 to 2018 for hip hop/rhythm and blues (R&B), pop, Latin, country, and rock/metal genres. Themes from songs were identified, quantified, and categorized with a rubric into negative, neutral, and positive themes by 3 different reviewers. Analysis was performed using 2-tailed t tests and a generalized linear model. Results Popular songs were reviewed for positive, negative, and neutral themes in the following 3-year intervals for ease of analysis purposes: 1998 to 2000 (n=148), 2001 to 2003 (n=150), 2004 to 2006 (n=148), 2007 to 2009 (n=156), 2010 to 2012 (n= 150), 2013 to 2015 (n=150), and 2016 to 2018 (n=150). There was a significant 180% increase in the percentage of songs with negative themes between all the interval years and across all genres (P<.001), while there was no significant difference in the frequency of songs with positive (P=.54) or neutral (P=.26) themes by year. There were significant differences in the number of negative themes found across genres (P<.001), with hip hop/R&B having the highest frequency of 130 out of 208 (62.5%) of the negative themes when compared to each of the individual genres (P<.001). Conclusions This study shows there is an increase in the frequency of negative themes over the span of 20 years across all genres, with hip hop/R&B having the highest frequency among the genres. These findings point to the potential impact that music may have in popular culture and on society. Furthermore, these results can help shape discussions between caregivers and their adolescent dependents and between primary care providers and their adolescent patients.

BACKGROUND The United States have seen an increase in depressive-anxious symptoms and suicidality in the past couple years within the adolescent population. The effects of pop culture, including music, is a factor that is worth exploring to better understand the context in which adolescents view themselves and society. OBJECTIVE This study analyzes the lyrics and music videos of the most popular music of multiple genres to better understand music theme trends. METHODS The frequencies of themes of 1052 total American and Latin songs were collected from the Nielsen Music and Billboard’s top 100 chart performance from 1998-2018 for Hip-Hop/R&B, Pop, Latin, Country, and Rock/Metal genres. Themes from songs were identified, quantified, and categorized using a rubric into negative, neutral, and positive by three different reviewers. Analysis was performed using two-tailed t-tests and a generalized linear model. RESULTS Popular songs were reviewed for positive, negative and neutral themes in three-year intervals for ease of analysis purposes: 1998-2000 (n=148), 2001-2003 (n=150), 2004-2006 (n=148), 2007-2009 (n=156), 2010-2012 (n= 150), 2013-2015 (n=150), and 2016-2018 (n=150). There was a significant increase between all the interval years in the percent of songs with negative themes by 180% across all genres (P=0.01), while there was no significance in the difference of frequency of songs with positive or neutral themes by year respectively (P=0.01). There were significant differences in the number of negative themes found across genres (P=0.01), with Hip-Hop/R&B having the highest frequency (62.5%) of negative themes when compared to each of the individual genres (P=0.01). CONCLUSIONS This study shows there is an increase in the frequency of negative themes over the span of 20 years across all genres, with Hip-Hop/R&B having the highest frequency compared to other genres. These findings point to the potential impact of music in popular culture on society and can help shape discussions between caregivers and their adolescents as well as the primary care provider and the adolescent patient.
