Plus, remembering feats by Paula Abdul, Mariah Carey & Hanson.
Your weekly recap celebrating significant milestones from more than seven decades of Billboard chart history.
May 20, 1989 30 years ago: The title cut from Paula Abdul's debut album Forever Your Girl spent its first of two weeks at No. 1 on the Billboard Hot 100. The set spun off four Hot 100 No. 1s in all.
May 21, 2011 Adele began the chart-topping reign that would net her the top song of the 2011 chart year, as "Rolling in the Deep" spent its first of seven weeks atop the Billboard Hot 100.
May 22, 2004 15 years ago: The bad news: Usher fell from the top spot on the Billboard Hot 100 after 12 weeks with "Yeah," featuring Lil Jon and Ludacris. The good news: he replaced himself at the summit with follow-up "Burn," which would reign for eight weeks.
May 23, 1998 Mariah Carey scored her lucky 13th Billboard Hot 100 No. 1 with "My All." She's since upped her total to 18 leaders, the most among all solo artists in the chart's history.
May 24, 1997 Its lyrics may have been somewhat nonsensical, but, thanks to its undeniable hook, Hanson's "MmmBop" became a smash, beginning a three-week stay atop the Billboard Hot 100.
May 25, 1991 More Mariah Carey, who notched her fourth Billboard Hot 100 No. 1 in as many tries from her debut self-titled album, as "I Don't Wanna Cry" reached the top spot. It followed "Vision of Love," "Love Takes Time" and "Someday" to the summit. Carey became the first act to top the Hot 100 with her first four entries on the chart since the Jackson 5 in 1970 and would lead with her next single, 1991's "Emotions," becoming the first artist to hit No. 1 with five initial singles.
May 26, 1984 35 years ago: Give it up for Deniece Williams! And, "Let's Hear It for the Boy," too, as her smash reached the top of the Billboard Hot 100.
