Pop star Janet Jackson scored her seventh No. 1 album on the weekly US Billboard 200 album chart on Monday (Oct 12), making her only the third musician to achieve a chart-topping record in each of the past four decades.

Unbreakable, Jackson's 11th studio album and the first after the 2009 death of her pop star brother Michael Jackson, sold 109,000 albums, 44,000 songs and was streamed nearly 4 million times in the week ending Oct 8, totaling 116,000 units according to figures from Nielsen SoundScan.

Last week's chart-topper, rapper Fetty Wap's self-titled record, dropped to No. 4 this week, behind R&B singer The Weeknd's Beauty Behind The Madness at No. 2 and rappers Drake and Future's What A Time To Be Alive at No. 3.
