Your weekly recap celebrating significant milestones from more than seven decades of Billboard chart history.

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
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. As Paul Grien wrote in Chart Beat that week (via reader David Harris), Carey became the first act to top the Hot 100 with her first four entries on the chart since the Jackson 5 in 1970. Carey would lead the list with her next single, 1991's "Emotions," becoming the first artist to hit No. 1 with his or her first five singles.

(On the same date, the Billboard 200 adopted Nielsen Music point-of-sale data, allowing, for the first time, a chart ranking album sales not by ranked retailer reports but electronically-scanned sales. No. 1 that week? Michael Bolton's Time, Love and Tenderness.)

May 26, 1984
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.

May 27, 1995
Hootie & the Blowfish's breakthrough album Cracked Rear View, featuring the monster hits "Hold My Hand," "Let Her Cry," "Only Wanna Be With You" and "Time," spent its first of eight weeks at No. 1 on the Billboard 200.
