Pop star Janet Jackson scored her seventh number one album on the weekly US Billboard 200 album chart on Monday, making her only the third musician to achieve a chart-topping record in each of the past four decades, Billboard said.

Unbreakable, Jackson’s eleventh 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 October 8, totalling 116,000 units according to figures from Nielsen SoundScan.

The only other artists to score a chart-topping record in each of the past four decades are Barbra Streisand and Bruce Springsteen.

Streisand and Madonna are the only other female artists to have more number one albums than Jackson, the former with 10 under her belt and the latter with eight, Billboard said.

The Billboard 200 chart tallies album sales, song sales (10 songs equal one album) and streaming activity (1,500 streams equal one album).

Last week’s chart-topper, rapper Fetty Wap’s self-titled record, dropped to number four this week, behind R&B singer The Weeknd’s Beauty Behind the Madness at number two with 73,000 units and rappers Drake and Future’s What A Time To Be Alive at number three with 65,000 units.

Only one other new album cracked into the top 10 this week, R&B singer Tamar Braxton’s Calling All Lovers at number five.

On the Digital Songs chart, which measures online download sales, Drake’s Hotline Bling ousted The Weeknd’s Hills for the top spot, selling 121,000 downloads in the past week.
