Considered one of Donna Summer’s standout songs , "No More Tears (Enough Is Enough)" was recorded with Barbra Streisand in 1979. The song became so popular that several vocalists have recorded their own versions over the years.

The former Beatle had already collaborated with the King of Pop on "The Girl Is Mine," featured on Jackson’s Thriller album. The song was so successful that they teamed up again to record "Say Say Say," the lead single from McCartney’s fourth solo album , Pipes of Peace .

Jackson wrote most of the lyrics, and the legendary George Martin produced the track. It was released in 1983 , along with a music video in which the duo plays a pair of con men selling a miracle potion. The video also featured cameos by Linda McCartney and La Toya Jackson.

Did you know this song wasn’t originally written as a duet? It was composed by Dennis Morgan and Simon Climie with Tina Turner in mind . Eventually, Aretha Franklin got the job, and the label later suggested a collaboration with George Michael.

Aretha and George released "I Knew You Were Waiting (For Me)" in 1987. Both artists later stated that they had a great time recording the song and the music video that followed. And it shows, because the tune reached number one on the Billboard Hot 100 and topped charts around the world.

The original version of this song was recorded in 1966 by C. Carson Parks and his wife, Gaile Foote, but it only became widely known in 1967 when Nancy Sinatra performed it with her father, Frank.

It may seem a little unusual for a father and daughter to sing a romantic duet, but their version of "Somethin’ Stupid" became a massive international hit . Although the song was revived in 2001 by another duo—British singer Robbie Williams and Australian actress Nicole Kidman—Nancy and Frank’s rendition remains the most iconic.

When the anti-disco backlash nearly ended their reign, the Bee Gees shifted their focus to writing hits for other artists. Originally, "Islands in the Stream" was intended as a soul song for Diana Ross or Marvin Gaye. However, it ended up becoming the quintessential country-pop duet—and one of the biggest hits of Kenny Rogers and Dolly Parton’s careers.

The song is named after Ernest Hemingway’s posthumous novel, but its lyrics speak to the joy of finding that one person you’ve been searching for your whole life. Pretty romantic, don’t you think?

Paul McCartney and Stevie Wonder released "Ebony and Ivory" in 1982, and it was an instant hit. Written by McCartney, the song addresses racial integration , using the black and white keys of a piano—working together to create harmony—as a metaphor.

Fun fact: McCartney and Wonder filmed their parts of the music video separately due to scheduling conflicts, but the final result was seamless nonetheless.

In 2015, a time capsule from 1944 was found beneath the City Hall stairs in Lebanon, New Hampshire. Inside was a whiskey bottle with a humorous note: "Whoever finds this bottle may keep it. Sorry, there is no liquor in it, but I drank it all up."

The note was signed by Samuel Stevens, a former city surveyor. Along with the bottle were old newspapers and a penny, but Stevens’ decades-old joke stole the spotlight.

In March 2015, a 19th-century time capsule was found in the cornerstone of a former telescope factory in Pittsburgh. It included what may be one of the first pieces of optical glass made in America .

The Brashear Company, founded by astronomer Dr. John A. Brashear, made telescopes and scientific tools from the 1880s to the early 1900s. By the 1940s, the site was used to produce bombsights for the U.S. military.

In 1983, Steve Jobs spoke at the Aspen Design Conference and added a computer mouse to the Aspen Time Tube , buried nearby. Meant to be opened in 2000, its location was forgotten over time.

In 2013, a National Geographic crew finally unearthed it. Along with the Lisa mouse, the capsule held a Rubik's Cube and a Moody Blues 8-track tape.

While technically, this is not a time capsule in strict terms, it can be seen as one. An American family inherited an old building from their grandparents and discovered a forgotten shoe store locked for decades .

The store, active from the 1940s to 1960s, held hundreds of vintage shoes in mint condition, possibly worth thousands. The family is keeping the location secret while they assess its full value.

Spooky message

In 2016, a time capsule from Montgomery Elementary in Albuquerque was found, containing notes from a 1968 fourth-grade class. Most messages were typical for kids at the time. But one stood out: Greg Lee Youngman began his note with "I am dead" and claimed he was born in 1900 . Whether he was imagining the distant future or pretending to be a ghost, it added a spooky twist.

While demolishing his parents' old barn, a man discovered a 128-year-old time capsule hidden beneath the rubble.

"Born to Run" (1975) - Bruce Springsteen

The list’s opener is a Springsteen anthem of escape that was not immediately destined to carry its famous title. In early drafts, the Boss called it "Wings for Wheels" . As the song evolved, the chorus took on a new intensity.

Switching to "Born to Run" sharpened the message, capturing the concept of youth that is expressed in the song.

2

"Hotel California" (1976) - Eagles

Before becoming a haunting allegory of excess, the track carried the placeholder name "Mexican Reggae." The band used that phrase to describe the unusual rhythm and guitar feel they had stumbled upon in rehearsal.

But when Don Henley and Glenn Frey shaped the lyrics, the story became much larger, and the now-classic title stuck.

3

"Good Vibrations" (1966) - The Beach Boys

Brian Wilson envisioned his experimental pop masterpiece under the simpler working title "Good Vibes." The phrase matched the psychedelic optimism of the era, but it didn’t quite sing.

By expanding to "Good Vibrations," Wilson captured the idea of mystical, almost spiritual energy.

4

"Free Fallin’" (1989) - Tom Petty

This timeless ballad started life with the less evocative title "It’s a Long Day," borrowed directly from the opening lyric of the second verse. The phrase, while descriptive, lacked the lyrical punch Petty wanted for a chorus.

As the song took shape, "Free Fallin’ " emerged as the hook that defined the track.

5

"Superstition" (1972)- Stevie Wonder

Stevie Wonder’s funk classic nearly went to press as "Very Superstitious. " That title echoed the first line and emphasized the theme, but it felt slightly clunky when repeated.

Stripping it down to "Superstition" lent the track greater impact. With it, the song became one of Wonder’s defining masterpieces.

6

"Respect" (1967) - Aretha Franklin

Aretha’s most famous song was nearly titled "Take Care, TCB," highlighting her famous line about "Taking Care of Business."

In the end, keeping it simply "Respect" made the track timeless. The title embodied empowerment and self-worth.

7

"What’s Going On" (1971) - Marvin Gaye

When Marvin Gaye began work on his masterpiece, the track carried the working name "What’s Happenin’ Brother." That phrase later became the title of a different song on the same album.

By renaming it "What’s Going On," Gaye gave the song broader resonance.

8

"Blowin’ in the Wind" (1962) - Bob Dylan

Bob Dylan’s folk anthem once had a far more literal title in mind: "Answer, My Friend." The phrase came from the chorus line that would become the song’s most quoted passage.

Choosing "Blowin’ in the Wind" turned a straightforward lyric into a metaphor for freedom and justice.

9

"Crazy" (1961) - Patsy Cline

Willie Nelson originally drafted this ballad under the blunt title "Stupid." Though catchy, it didn’t capture the tenderness he wanted for the song.

Delivered with Patsy Cline’s aching vocals, "Crazy" became a country standard and one of the most recorded ballads of its era.

10

"Born in the U.S.A." (1984) - Bruce Springsteen

This track was first conceived under the stark working title "Vietnam." Its focus was originally narrower, highlighting the struggles of veterans returning home from war.

By renaming it "Born in the U.S.A.," Springsteen expanded the scope. The patriotic-sounding title created a powerful contrast with the song’s harsh lyrics.

11

"Material Girl" (1985) - Madonna

Written by Peter Brown and Robert Rans, the pop hit almost debuted as "Living in a Material World." The longer phrase fit the chorus but lacked the commercial hook they wanted.

Shortening it to "Material Girl" made all the difference. The title captured Madonna’s persona — a moniker that stuck with her for the duration of her legendary career — and helped define an era.
