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

Aug. 27, 2011
Katy Perry scored a fifth Billboard Hot 100 No. 1, "Last Friday Night (T.G.I.F.)," from her album Teenage Dream, marking an historic coronation: the set joined Michael Jackson's Bad, in 1987-88, as the only albums ever to generate five Hot 100 No. 1s each.

"Hitting No. 1 is always a great moment, but when it turns into a small piece of history, you're reminded of how many millions of people are connected to each other by even one tiny event," Perry told Billboard upon learning of the achievement. "Ever since I was 9 years old, singing into my hairbrush, I've dreamed very big dreams, but today is bigger than my dreams."

Aug. 28, 1976
Billboard's Dance Club Songs chart began as a national weekly survey, capped initially by the Bee Gees' "You Should Be Dancing," certainly an appropriate title to lead the first list.

Aug. 29, 1987
"La Bamba," Los Lobos' title track to the biopic of late legend Ritchie Valens, crowned the Billboard Hot 100 for the first of three weeks. The classic original had hit No. 22 in 1959.

Aug. 30, 1997
After Diddy (then Puff Daddy) and Faith Evans' ode to slain rapper The Notorious B.I.G., "I'll Be Missing You," led the Billboard Hot 100 for 11 weeks, Biggie himself took over atop the list posthumously, as his "Mo Money Mo Problems," featuring Diddy and Mase, began a two-week reign.

Aug. 31, 1996
On the Billboard Hot 100, it peaked at No. 2 for nine weeks, below Los Del Rio's juggernaut "Macarena (Bayside Boys Mix)." On the Pop Songs airplay chart, however, Donna Lewis' "I Love You Always Forever" would not be denied, as it began an 11-week rule.

Sept. 1, 1984
After 20 Billboard Hot 100 entries as half of Ike & Tina Turner in 1960-75, and her first solo hit ("Let's Stay Together") earlier in 1984, the legendary diva topped the Hot 100 at last with "What's Love Got to Do With It," which would lead the list for three weeks.

Sept. 2, 1995
Michael Jackson's "You Are Not Alone" became the first song ever to debut at No. 1 on the Billboard Hot 100. The ballad became the last of Jackson's 13 solo leaders (following four Jackson 5 No. 1s).
