If I were asked to name some of the most iconic songs of all time, I'd probably throw out titles like "Somewhere Over the Rainbow," or "Hey Jude." Turns out science has a different answer. Researchers from Goldsmiths, University of London put "Smells Like Teen Spirit," by Nirvana at the top of a list of 50 iconic tunes. It's followed by John Lennon’s “Imagine," U2’s “One,” Michael Jackson’s “Billie Jean,” and Queen’s “Bohemian Rhapsody.”
Computer scientist Dr. Mick Grierson looked at tracks found in seven "Best of" lists from music publications like Rolling Stone and ran them through a program that compared them by key, BPM, chord variety, lyrical content, timbral variety, and sonic variance. Grierson and his team used these findings to calculate what made the "perfect" song.
“We found the most significant thing these songs have in common is that most of them use sound in a very varied, dynamic way when compared to other records,” Grierson told the Daily Mail. “This makes the sound of the record exciting, holding the [listeners'] attention. By the same token, the sounds these songs use and the way they are combined is highly unique in each case.”
Nirvana's breakout track, featured on their second studio album Nevermind, boasts many of the features that the researchers identified as common in popular songs.
Grierson found that the average tempo of the most popular songs was 125BPM, with 40 percent being around 120BPM. Chord changes were relatively infrequent—the songs that fared the best boasted an average of six to eight. Of course, there are some glaring exceptions to these "rules": Led Zepplin's "Stairway to Heaven" has twice as many beats as the average song.
Ultimately, the researchers found that no amount of number-crunching can accurately predict whether or not a song will become a classic. "My conclusion is that if you want a formula for creating great music, there is one: you just have to make something that sounds great," Grierson says.

Since 2016, Radiolab's More Perfect podcast has taken what is typically viewed as a dry subject, the Supreme Court, and turned it into an engrossing podcast. Now, fans of the show have a whole new way to learn about the parts of U.S. history which textbooks tend to gloss over. 27, The Most Perfect Album, a new music compilation from Radiolab, features more than two dozen songs inspired by each of the 27 amendments to the U.S. Constitution, from freedom of religion to rules regulating changes to Congressional salaries.
More Perfect assembled an impressive roster of musical talents to compose and perform the tracklist. They Might Be Giants wrote the song for the Third Amendment, which prohibited the forced quartering of soldiers in people's homes. It goes, "But the presence of so many friendly strangers makes me nervous, and it does not mean that I'm not truly thankful for your service."
For the 19th Amendment, which gave women the right to vote, Dolly Parton sings, "We carried signs, we cursed the times, marched up and down the street. We had to fight for women's rights with blisters on our feet." Less sexy amendments, like the 12th Amendment, which revised presidential election procedures, and the 20th Amendment, which set commencement terms for congress and the president, are also featured. Torres, Caroline Shaw, Kash Doll, and Cherry Glazerr are just a handful of the other artists who contributed to the album.
The release of the compilation coincides with the premiere of More Perfect's third season, which will focus on the 27 amendments to the U.S. Constitution. You can check out the first episode of the new season today and download the companion album for free through WNYC.
In the winter of 1956, Chrysler unveiled a series of improvements to their lineup of automobiles. There was LifeGuard, a latch that prevented doors from flinging open in the event of an accident. New windshield wipers promised to clean 10 percent more of the glass surface than the previous year’s model. And for those consumers willing to spend an extra $200—the equivalent of about $1700 today—there was the Highway Hi-Fi, a factory-installed record player mounted under the car's dashboard.
Using an “elastic three-point suspension,” the unit played “non-breakable” 7-inch records. In advertising copy, Chrysler touted that the discs would never skip, not even during sharp turns or while crossing railroad tracks. “It’s almost impossible to jar the arm off the record,” the company promised, anticipating the dubious looks of dealers and buyers alike.
As it turned out, attempting to spin a record while in a moving vehicle was every bit as problematic as it might sound. But before 8-tracks, cassettes, CDs, and satellite radio, the Highway Hi-Fi represented the first opportunity for drivers to have some control over what they were listening to. They had autonomy—freedom to deviate from radio programmers, invasive ads, and boring talk shows.
Naturally, radio stations hated the idea.

This bizarre automotive alteration was the result of an engineering genius who wanted to get his kid to shut up. Peter Goldmark was head of CBS Labs, a position which afforded him the resources to pursue other innovations. (He’s widely credited with ushering in the modern system of broadcasting color television.) He was the inventor of long-play (LP) records, which played vinyl at 33 and one-third revolutions per minute (RPM) instead of 78. Introduced in 1948, LPs revolutionized the music industry, packing more information onto the 12-inch discs by etching microgrooves into the vinyl and allowing producers to place up to 60 minutes of music on a side.
In the 1950s, Goldmark’s son observed that drivers had no influence over what was being broadcast via the transistor radios that had become standard in vehicles. While you could switch stations, you were still at the mercy of programming directors and their tastes in music.
As inventors tend to do, Goldmark identified the problem and then sought out a way to remedy it. His own creation, the LP, was far too big to have any practical application in a vehicle: The turntable would hang over a passenger’s knees. The 45 RPM record was much smaller but could only hold about five minutes of music on each side. Forcing someone to try and change records with such frequency while driving would likely result in accidents.
Goldmark devised a new option. Using a 7-inch record, he created a surface with ultra-microgrooves that played at 16 and two-thirds RPM. Each side could hold 45 minutes of music, a far more practical solution for people who couldn’t tend to the turntable easily. It also fit snugly under the dash, projecting out at the push of a button so the user could load a record and set the needle before pushing it back underneath and out of the way.
Goldmark made other adjustments. The vinyl records were thicker than standard LPs so they would be more heat-resistant during the summer months. He also developed a spring enclosure to absorb shocks and a counterweighted needle arm to make sure it wouldn’t leap off the record while traveling over bumps.
Goldmark tested it in a CBS executive’s Thunderbird. It worked flawlessly. He loved it.
CBS CEO William Paley hated it.
Paley equated the innovation to a form of self-sabotage. CBS had radio affiliates all around the country beaming their signals into millions of cars; those stations sold advertising spots to generate revenue. If drivers began listening to their own records instead of the radio, they were effectively diluting their own audiences. Paley thought sponsors would have a tantrum. He dismissed the idea entirely.
Perhaps feeling slightly petulant, Goldmark instead went directly to his potential customer: a car manufacturer. Visiting with Chrysler executive Lynn Townsend, Goldmark sold the company on the dashboard record player as a factory option. He rode along during a test drive, with Chrysler employees driving over bumps, railroad tracks, and other obstacles to see if the record skipped. It didn’t. The company ordered 18,000 Highway Hi-Fi units, a sizable investment that Paley couldn’t ignore.
CBS Labs mass-produced the devices, and Chrysler began instructing their dealers to pitch the add-on to prospective buyers. Each unit would come with six records, with the option to buy more through CBS-Columbia, a record label that manufactured the unique discs. Owing to Paley’s influence—he detested rock music—the choices were extremely placid. Car owners got the soundtrack to the Pajama Game Broadway musical, some Tchaikovsky, a jazz record, a dramatic reading of a George Bernard Shaw play, and songs from Disney’s Davy Crockett television series. (The latter was advertised to “help keep [kids] quiet.”) The catalog offered spoken-word reenactments of the Battle of Gettysburg.
Owing to their smaller grooves, the records couldn’t be played on conventional turntables. Given the selection, that was probably a blessing.

The limited selection was one problem. The functionality of the Highway Hi-Fi was another. Goldmark had tested the device in a Thunderbird and in high-end Chrysler vehicles, but the company offered the machine in their economical Dodge and Plymouth models, which both had modest shock absorption. The records could and did skip, and the models were the source of several claims against the car’s warranty coverage. Local mechanics weren’t audiophiles and didn’t have the knowledge to make simple repairs. As word spread, Chrysler went from selling 3685 Hi-Fi units in 1956 to just 675 in 1957.
The option was discontinued shortly thereafter, but that wasn’t quite the end for car-mounted records. In 1960, RCA thought they had resolved some of the outstanding issues with their Victrola, which played 45s and overcame the short running time problem by constructing a 14-disc changer. When one record was finished, the unit would automatically drop another in its place. Similar to a jukebox, the needle was upside down and the record lowered on top of it to reduce skipping. Records slid into a slot in a manner similar to the CD players that were decades away.
The Victrola was picked up by Chrysler. It performed better than the Highway Hi-Fi, was cheaper ($51.75), and didn’t force users to limit themselves to the paltry selection of CBS’s custom discs. But it didn’t last long either; it was discontinued in 1961. (Another option, the UK’s Auto-Mignon, played 45s with manual switching: Each of the four Beatles was said to own one.) Before anyone could think to improve upon it further, 8-tracks arrived and soon became the portable car sound source of choice. CBS never followed through on plans to equip taxis, airplanes, buses, and other forms of transportation with their devices. In the evolution of on-demand music and auto transportation products, the Highway Hi-Fi was one step best skipped.
