▶ Listen to the Decade's Number Ones

The Billboard Hot 100 had 253 different 70s number one hits, and the Bee Gees scored the most of them, nine.

Debby Boone's You Light Up My Life held the top spot longest, 10 straight weeks in 1977.

Those songs filled 522 weekly charts, from January 3, 1970 to December 29, 1979.

Every one is in the sortable table below, and 237 of them play right here from official artist and label uploads.

The Short Answer: 253 Songs, 522 Weeks

The 1970s turned over the top of the chart faster than most people remember.

Here is the decade in numbers:

• 253 different songs reached number one.
• 522 weekly charts were published, because 1972 and 1977 each had 53 chart weeks.
• 125 songs lasted exactly one week at the top.
• 59 more lasted exactly two weeks.
• 13 songs lost the top spot and then won it back.

So almost half the decade's chart-toppers were gone after seven days.

That churn is the real story of the era.

AM radio, disco clubs and a flood of soft rock all fed the same single chart.

A song could own the country on Saturday and be yesterday's news by the next one.

The First and Last 70s Number One Hits

B.J. Thomas opened the decade with Raindrops Keep Fallin' on My Head.

It sat at number one on the very first chart of 1970, dated January 3, and held on for four weeks.

The song came from the soundtrack of Butch Cassidy and the Sundance Kid.

Rupert Holmes closed it out with Escape (The Piña Colada Song), number one on the chart dated December 29, 1979.

One is a breezy movie song.

The other is a wry story song about answering a personal ad.

Everything else in the 70s happened between those two records.

The Longest-Running Chart-Toppers

Only ten songs of the decade held the top for six weeks or more.

Weeks are counted from the weekly charts themselves, and a song's separate runs are added together.

Debby Boone's 10 Straight Weeks

You Light Up My Life took over on October 15, 1977 and did not let go until the week ending December 23.

That was ten consecutive weeks, the longest single run of the decade.

It was a hushed, churchy ballad in the middle of the disco boom.

You can see the run for yourself on Billboard's own Hot 100 chart for October 15, 1977.

1978, the Year of the Gibb Brothers

Three of the ten longest runs belong to 1978.

Two of those came from one family.

Night Fever gave the Bee Gees eight weeks, and Shadow Dancing gave their younger brother Andy Gibb seven more.

Chic's Le Freak arrived in December and was still trading the top spot in February 1979.

Which Artists Had the Most Number Ones

The Bee Gees own this category outright.

They scored nine number ones in the 1970s and spent 27 weeks on top.

The Bee Gees' Nine

Their run started as a soft-rock ballad group and ended as the sound of disco itself.

• How Can You Mend a Broken Heart (1971): 4 weeks
• Jive Talkin' (1975): 2 weeks
• You Should Be Dancing (1976): 1 week
• How Deep Is Your Love (1977): 3 weeks
• Stayin' Alive (1978): 4 weeks
• Night Fever (1978): 8 weeks
• Too Much Heaven (1979): 2 weeks
• Tragedy (1979): 2 weeks
• Love You Inside Out (1979): 1 week

The full story of the group behind that list is on the Bee Gees artist page.

Why Elton John and Paul McCartney Look Smaller Than They Were

The table counts each artist exactly as the chart credited them.

Two stars split their number ones across more than one credit.

• Elton John: four as Elton John, plus Philadelphia Freedom as the Elton John Band and Don't Go Breaking My Heart with Kiki Dee.
• Paul McCartney: one with Linda McCartney, two as Paul McCartney and Wings, and three as Wings.

Add those up and both men reach six apiece.

That still leaves them three behind the Bee Gees.

Number Ones Year by Year

The number of new chart-toppers swung hard from year to year.

The table counts each song in the year of its first week at number one, and each year links to its full year-end chart page.

The year-end No. 1 is the song Billboard ranked first for the whole year, which is not always the song with the longest run.

The Revolving Door of 1974 and 1975

In 1974 and again in 1975, 35 different songs reached number one.

That is a new chart-topper roughly every week and a half.

These were the years of one-week wonders, novelty records and early disco singles all trading places.

The Blockbuster Years of 1971 and 1978

At the other end, 1971 had only 18 new number ones and 1978 had 19.

Fewer new songs meant longer runs.

In 1978 that was the Saturday Night Fever effect, with the Gibb family holding the top for weeks at a time.

Number Ones by Date

Every Billboard chart of the decade carries a Saturday issue date, so any day of the 1970s falls inside exactly one chart week.

The Birthday #1 Song Finder takes any 1970s date and shows the song that was on top that week.

This Week in Music History, Date by Date

These pages take one calendar date and list every number one that held the top on it across all ten years of the decade.

• January 9

• February 13
• March 20
• April 17
• May 1
• May 29
• June 12
• July 15
• August 19
• September 16
• October 8
• October 24
• November 7
• November 12
• November 19
• November 28
• December 3

Each date page lines the songs up year by year, so the same week can be heard from 1970 to 1979 in one sitting.

Songs That Lost the Top Spot and Came Back

Thirteen of the 70s number one hits fell from the top and then climbed back up.

• Alone Again (Naturally), Gilbert O'Sullivan
• Killing Me Softly with His Song, Roberta Flack
• Let's Get It On, Marvin Gaye
• The Way We Were, Barbra Streisand
• Fame, David Bowie
• That's the Way (I Like It), KC and the Sunshine Band
• Silly Love Songs, Wings
• I Just Want to Be Your Everything, Andy Gibb
• Best of My Love, The Emotions
• You Don't Bring Me Flowers, Barbra Streisand and Neil Diamond
• Le Freak, Chic
• I Will Survive, Gloria Gaynor
• Hot Stuff, Donna Summer

Barbra Streisand is the only name on that list twice.

Notice how many of them are dance records.

A club hit could fade on radio, keep packing floors, and surge back a few weeks later.

How This List Was Built

Every figure on this page comes from this site's weekly Billboard Hot 100 file, one record per chart week.

There are 522 records, with no missing weeks between January 3, 1970 and December 29, 1979.

Weeks Are Counted From the Charts Themselves

The data file also stores a separate "weeks at number one" figure for each song.

For nine songs, that stored figure disagrees with the weekly charts.

Stevie Wonder's Superstition, for example, is stored as two weeks but appears on only one chart.

So every week count here comes from counting the actual charts, never the stored figure.

Checked Against Outside Sources

The yearly totals were compared with Billboard's own archive charts and Wikipedia's yearly lists, all named under Sources below.

The 1970 total of 21 different chart-toppers matches, as does the 35 for 1975.

The full approach is written up on the site's methodology page.
