These graphs show the sonic "fingerprints" of the Top 10 summer hits for eight years, selected from the fingerprints for 1988 - 2018. Each line represents a different song from that year so you will see 10 lines, each representing a top hit. The bold line is a song that was a top hit that year, just to give you an idea of what was popular that year. Use the example for Gloria Estefan's "1-2-3" below to understand how to read the fingerprints. The graphs were originally presented in NYTimes.com
