Do chart-topping tunes reveal anything about society? Yes, says one music expert

March 31, 2026

My fascination with pop music charts began at age 10. Every Sunday morning, I listened to “American Top 40 with Casey Kasem.” The syndicated radio countdown show was based on the Hot 100 singles tally from Billboard, the music trade magazine. I might have been the only pre-teen among my peers with a subscription.

Wherever the family went, I brought my portable Sony Walkman tuned to a SoCal affiliate station, headphones, a notepad and pen — all ready to jot down artists, song titles and the weekly chart positions for four hours. Then I meticulously designed a colorful chart and hung it on the wall. This endeavor continued until my junior year of high school when my priorities and taste in music shifted, but that early attention to detail would later serve me well as a journalist.

Flashing forward to the present, “Uncharted Territory: What Numbers Tell Us About the Biggest Hit Songs and Ourselves” (Bloomsbury) immediately drew my curiosity. While absorbing those countdowns as a kid, I was always fascinated by the songs’ chart trajectories and backstories. The book enlightened me about why a variety of factors determined the musical compositions’ popularity.

Author Chris Dalla Riva examines Billboard No. 1 pop hits from the past six decades, and provides thought-provoking insights. It is geared toward past or present pop chart enthusiasts like me, trivia buffs, casual music listeners and beyond.

Back in 2017, Dalla Riva, a self-described musician and data junkie, was an economic consultant who wanted another musical outlet in his life. After coming across a Spotify playlist of every Billboard chart topper since 1958 (when the ranking first appeared), Dalla Riva decided to listen to them chronologically.

He tracked the tunes’ songwriters, producers, time signatures, lyrical complexities, and various facts in a spreadsheet. An example of the latter: I was quite surprised to discover the Golden State is one of only four states to appear in the title of a No. 1 single, and that there weren’t more songs besides the Eagles’ “Hotel California,” 2Pac feat. Dr. Dre’s “California Love,” and Katy Perry feat. Snoop Dogg’s “California Gurls.” Moreover, New York didn’t even make the cut (the other states were Georgia, Kansas and Texas).

Having amassed “a giant data set,” Dalla Riva noticed some trends. “I felt compelled to start writing about them,” he wrote. “From there, a book slowly began to emerge over a handful of years.” He uses the information to tell the story of American popular music through musical, historical and analytical lenses.

Dalla Riva rated the tunes on a scale of 10 and later recruited willing family, friends and colleagues to help evaluate up to 25 songs. “That was the fun part. It was certainly a personal journey to some degree, but [also] a good reminder of the communal nature of music and how important it is to share songs with other people,” he told me in a video interview from his home in New Jersey.

The results comprise the end of each book chapter, divided into what the author terms highlights, lowlights, argument starters, odd and ends and everything else from each era, stopping at January 2025 (1,176 songs in total).

He wanted to find out how each became popular and discuss what “tied these songs into a larger conversation about bigger topics.” In the 1960s, for instance, then-seemingly innocuous lyrics to such big hits as Elvis Presley’s “Stuck on You,” Ricky Nelson’s “Travelin’ Man” and Johnny Preston’s “Running Bear” could be considered predatory or stereotypical — and therefore offensive — in today’s society. Another chapter delves into a group of socially conscious songs later that decade spurred by the Vietnam War, civil rights and assassinations.

“Uncharted Territory” is also frequently infused with humorous footnotes, easy-to-decipher graphs and charts, plus personal tales from Dalla Riva’s own life, including how his 10th grade mind was blown after his father played a Bruce Springsteen demo of “Growin’ Up.”

Dalla Riva does an excellent job at providing a condensed music history where even a veteran music journalist can still learn a few things, such as the drum machine’s development and influence on my favorite music period, New Wave of the early to mid-1980s.

Other notable subject matter includes the Beatles’ and Bob Dylan’s influence on music, short-lived trends (surf rock, dance crazes), how Billboard shifting to Soundscan point-of-sale data transformed the charts during the early 1990s, copyright infringement, the rise of sampling and much more.

After tearing through “Uncharted Territory” in a weekend — it’s a really fun and easy read, with a comprehensive bibliography and index — I gained an even better understanding about the reasons why so many popular songs have become an integral part of our lives.

All told, Dalla Riva wants readers to “listen to some songs they never heard before; both good and bad. That’s a goal of mine. I like to share music with people, so I hope that’s the case. The through line is how technology impacts popular music over and over again throughout the decades, from the establishment of recording to radio and streaming.”
