Bubbling Under Hot 100 Singles (also known asBubbling Under the Hot 100) is a chart published weekly byBillboard magazine in the United States. The chart lists the top songs that have not yet charted on the mainBillboard Hot 100. Chart rankings are based on radio airplay, sales, and streams. In its initial years, the chart listed 15 positions, but expanded to as many as 36 during the 1960s, particularly during years when over 700 singles made theBillboard Hot 100 chart. From 1974 to 1985, the chart consisted of 10 positions; since 1992, the Bubbling Under Hot 100 Singles chart has listed 25 positions.
The Bubbling Under Hot 100 Singles chart was introduced in the June 1, 1959, issue ofBillboard, under the name "Bubbling Under the Hot 100".[1] Containing a listing of 15 singles, the chart was described as "the new listing that predicts which new records will become chart climbers." Its first number-one single was "A Prayer and a Juke Box" byLittle Anthony and the Imperials[1] (the song would later peak at number 81). It would continue to be published in issues ofBillboard until August 24, 1985, after which it was discontinued.[2] Prior to its discontinuation, the chart had not been issued in four issues; three from 1974 and one in 1978.[3] However, it returned as a feature in the December 5, 1992, issue ofBillboard, and continues to the present day.[3] From the end of 1970 to 1985, there was aBubbling Under the Top LPs album chart paired with the Bubbling Under the Hot 100 listing.
From June 1959 through August 1985,Billboard compiled the chart based on playlists reported by radio station and retail sales outlets surveys. In 1992,Billboard employed updateddata capture technology in compiling the chart, using point-of-sale retail information provided byNielsen SoundScan, input from radio station airplay monitoring provided by Broadcast Data Systems and playlists from small-market systems.
The chart's first issue mentions that a rank position indicates "relative potential to earn an early listing on the Hot 100"[1] and records were ranked starting with number 1. From August 28, 1961, to August 24, 1985, the chart positions were numbered starting with number 101.[4] Songs that have already appeared on the Hot 100 are not included in the Bubbling Under chart as they exit the charts, but may re-enter the Bubbling Under chart at a later date.
Over the years, the chart would undergo several changes and alterations. In the 1960s, the chart included as many as 35 slots; on two rare occasions in 1963 and 1968, the chart contained 36 slots.[5][6] By the 1980s, the chart contained only 10 slots.[2] On the first issue of its 1992 revival, the chart was renamed to "Bubbling Under Hot 100 Singles" from its previous name, "Bubbling Under the Hot 100". The same issue increased the total number of slots on the chart to 25 and the chart numbering began with the number 1.
Several reference books on the history of theBillboard "Bubbling Under" charts have been published by chart statisticianJoel Whitburn's company Record Research. The latest book to be published by the company was 2005'sBubbling Under the Billboard Hot 100: 1959–2004 (ISBN978-0-89820-162-8). Whitburn's bookTop Pop Singles, 12th Edition (ISBN978-0-89820-180-2), covers allBillboard Hot 100 and Bubbling Under Hot 100 Singles chart entries from 1955 to 2008.
Released in 1982, "Nasty Girl" byVanity 6 spent a record-tying seven weeks at number 101, but never cracked theBillboard Hot 100.[3]
American rapperYoungBoy Never Broke Again holds the record for having the most "bubblers" of any artist, charting 104 (58 of them reaching the Top Ten) of them from 2017 to 2024. Before the addition of streaming services to Billboard charts in the 2010s, the record was formerly held by American soul singerRay Charles, charting 15 from 1963 to 2005.[3]Tina Turner appears as an artist on 16 bubblers, 13 as one-half ofIke & Tina Turner, and three as a solo artist. Similarly, Joel Whitburn also gives credit for 15 bubblers toGeorge Clinton'sParliament/Funkadelic aggregation, which issued records under a variety of band names or solo identities. On the Bubbling Under charts, the loose-knit group appeared three times as Parliament, once as The Parliaments, three times as Funkadelic, once asThe Brides of Funkenstein, twice as Bootsy's Rubber Band, once under the name ofWilliam "Bootsy" Collins, and four times under George Clinton's name.[20] It could be argued that at least some of these groups are actually separate (though related) artists, however Whitburn lists them as one act under multiple aliases.
The Robbs hold the record for the act with the most appearances on the Bubbling Under chart without having any of their songs cross over into the Hot 100. Between 1966 and 1971, six of the group's singles appeared on the bubbling under charts. Their best showing was 1966's "Race with the Wind", which peaked at number 3.[3]Slipknot comes in second place with five. Their highest peaking single is "Psychosocial" at number 2.[21]
During the 1960s, there were as many as 35 slots in the Bubbling Under chart (with two exceptions; see below). Forty-three different songs grabbed the very bottom rung by peaking at number 135, including tunes from Donovan ("Summer Day Reflection Song"),Doris Day ("Send Me No Flowers"),The Applejacks ("Tell Me When", a Top 10 UK hit) and two fromSammy Davis Jr. ("Bee-Bom" and "If I Ruled The World").The Nightcrawlers cult classic "The Little Black Egg" peaked at number 135 in 1965, but was re-released and cracked the Hot 100 (at number 85) two years later.Shirley Ellis also hit number 135 with "Ever See A Diver Kiss His Wife While The Bubbles Bounce About Above The Water?", the longest-titled song ever to "bubble under". ("Coal Man", bySir Mack Rice, is the only song to spendtwo weeks at number 135, and peak there, in 1969.)
The chart contained 36 positions on two occasions. The two records that appeared at number 136 were "The Bounce" byThe Olympics (April 6, 1963; the song eventually hit number 40)[5] and "Turn Around, Look at Me" byThe Vogues (May 25, 1968; a huge hit that peaked at number 7).[22]
One of the most mysterious records ever to appear in anyBillboard chart was "Ready 'n' Steady", listed as recorded by an artist named "D. A.", which spent three weeks on the Bubbling Under chart in June 1979. In a 1995 interview, chart statisticianJoel Whitburn stated that "Ready 'n' Steady" was "the only record we've never been able to find in the history of the pop charts."[23] In the 4th edition of Whitburn's bookBubbling Under the Hot 100, published in 2005, the entry for "D. A." was amended with a note stating "the existence of this record and artist is in question." One of the more recent editions of Whitburn's bookBillboard's Top Pop Singles 1955–2010, published in 2011, includes both Top 100 and Bubbling Under singles, but D. A. was not listed.[24] In 2016, researcher Paul Haney finally located a tape recording of the song but determined that it had never been pressed onto a vinyl record or commercially released in any form, and that arecord promoter had nevertheless managed to get the song on theBillboard chart. "D. A." was Dennis Armand Lucchesi (June 5, 1945 – August 18, 2005), a California-based mortgage broker and part-time musician.[25]
