"Teenage Dream" yielded its fifth Hot 100 No. 1, matching the mark that Jackson first set with "Bad." Plus, remembering feats by Taylor Swift, Eve & the Bee Gees.

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

Aug. 22, 2009
Seven years ago, Taylor Swift took over atop Hot Country Songs with "You Belong With Me," her fourth of seven leaders on the survey. The song would also go on to crown the all-format Radio Songs chart for two weeks, becoming the first country crossover track to rule the ranking. It also led Adult Contemporary for a whopping 14 frames, marking her longest reign among six No. 1s at the format.

Aug. 23, 1969
The Rolling Stones scored their fifth and final Billboard Hot 100 No. 1 of the '60s (of eight overall) with "Honky Tonk Women."

Aug. 24, 1985
Let's go Back to the Future: Huey Lewis & the News topped the Billboard Hot 100 with "The Power of Love," their theme from the Michael J. Fox time-travel blockbuster.

Aug. 25, 2001
Eve's "Let Me Blow Ya Mind," featuring Gwen Stefani, hit No. 1 on the Pop Songs airplay chart. In 2005, the stars would reteam (with Stefani in the lead role) for "Rich Girl," a No. 4 Pop Songs hit. On the Billboard Hot 100, the songs reached Nos. 2 and 7, respectively.

Aug. 26, 1995
Batman Forever spurred Seal's sole Billboard Hot 100 No. 1: "Kiss From a Rose."

Aug. 27, 2011
Five years ago, 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 (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. Thank you to everyone who helped make this happen," Perry told Billboard that week in 2011 upon learning of her 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."

Meanwhile, Perry, aka, Kathy Beth Terry, wrangled a host of guests for the mini-movie video for "T.G.I.F.," including Rebecca Black, Darren Criss, Kevin McHale, Hanson, Kenny G, Corey Feldman and Debbie Gibson (the latter two as her '80s alter-ego's parents … Kirk and Tiffany).

Aug. 28, 1976
On this date 40 years ago, 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.
