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

Feb. 10, 1990
Paula Abdul and her cartoon pals the Wild Pair began a two-week reign atop the Billboard Hot 100 with "Opposites Attract," the fourth and final No. 1 from her debut album "Forever Your Girl." Almost exactly a year earlier (Feb. 11, 1989), "Straight Up" became the set's first leader.

Feb. 11, 1989
... In addition to Abdul's rule with "Straight Up": After an American student visiting Europe brought back a copy of the song to the U.S., spurring interest at stateside radio, Roxette soared onto the Billboard Hot 100 at No. 50 with its eventual first No.1 "The Look." Other debuts that week: Thirty Eight Special's "Second Chance," Traveling Wilburys' "End of the Line" and (former Billboard publisher) Tommy Page's "A Shoulder to Cry On."

Feb. 12, 2005
Rascal Flatts began their longest command of Hot Country Songs, as "Bless the Broken Road" spent its first of five weeks at No. 1.

Feb. 13, 1999
Whitney Houston notched her eighth and final No. 1 on Hot R&B/Hip-Hop Songs, as "Heartbreak Hotel," featuring Faith Evans and Kelly Price, began a seven-week domination.

Feb. 14, 1987
Bon Jovi enjoyed a rockin' Valentine's Day 27 years ago, as "Livin' on a Prayer" rose to No. 1 on the Billboard Hot 100.

Feb. 15, 1969
Funk pioneers Sly & the Family Stone scored their first of three Billboard Hot 100 No. 1s with "Everyday People." They'd later lead with "Thank You Falettinme Be Mice Elf Agin" (1970) and "Family Affair" (1971).

Feb. 16, 1985
After arriving with the uptempo Billboard Hot 100 No. 1 "Wake Me Up Before You Go-Go," Wham! ruled again with ballad "Careless Whisper." Last month, the duo's George Michael announced that his sixth solo album, "Symphonica," is due March 17.
