perfect sense on a thematic as well as sonic level, like Kool & the Gang's "Kool It (Here Comes the Fuzz)" and Stevie Wonder's "Superwoman, Where Were You When I Needed You" on "New Agenda," or the orchestral flourish from Diana Ross & the Supremes' "Someday We'll Be Together" on "If," which seems to exist for the sole purpose of providing the impetus behind one of the greatest dance-break routines in music video history." Commenting on the album's broad range, he states: "The mother of eclectic, genre-hopping records by Christina Aguilera, Gwen Stefani, and Fergie, janet. incorporates new jack swing, house, pop, rock, hip-hop, jazz, and even opera, but the album's range of styles isn't jarring in the least ... Janet has never been one thing and janet. is a feminist statement, to be sure." Alex Henderson of AllMusic offered a positive review, saying "[a]nyone who expected Jackson to top Rhythm Nation—her crowning achievement and an incredibly tough act to follow—was being unrealistic. But with janet., she delivered a respectable offering that, although not as strong as either Control or Nation, has many strong points." Commercial performance Janet debuted at number one on the Billboard 200 and the Top R&B/Hip-Hop Albums charts. It was the first a female artist debuted at number one since the start of the SoundScan era; with the largest first week sales in history for a female artist at the time with 350,000 units sold in its first week. The album also earned worldwide success, debuting at number one in the United Kingdom, New Zealand, and Australia. It also debuted in the top 10 in Sweden, The Netherlands, Canada (with 65,000 copies sold at the first week) and Switzerland. In Germany the album peaked at number five and charted for 49 total weeks, becoming Jackson's longest charting album. Janet was first certified gold by the RIAA on August 8, 1993, denoting 500,000 units shipped within the United States. The same day, the album's certification was raised to 3× platinum, denoting 3,000,000 units shipped. On November 17, 1993, Janet received 4× platinum certification and was later awarded 5× platinum on December 17, 1993. The following year on April 12, 1994, the album was certified 6× platinum. It was the second best selling album of 1993 in United States with 4.3 million copies sold, behind The Bodyguard soundtrack and was the biggest selling album by a solo artist.
