Jackson worked with producers such as Darkchild, Ne-Yo, Shea Taylor, Stargate, Johntá Austin, Jermaine Dupri, Tricky Stewart, and The-Dream on the album.

[5] The song "So Much Betta" contains sampled portions of the track "Daftendirekt" by the French house music duo Daft Punk.

[7] The first chapter, entitled "Photo Shoots", shows Jackson creating a new image for the album and adopting different looks for different markets.

She spent two days working on photos for the cover and credit booklet, revealing that she still feels uncomfortable in front of the camera despite two decades in the music industry.

In the second chapter, "The Studio", Jackson expressed her opinion on recording work, stating that although she usually enjoyed the experience, it was, at times, tedious.

The song's chorus compares her body to instruments such as a guitar and amplifier, using metaphors to demonstrate sexual climax.

[13] It's followed by "Luv", an electro-R&B song described as a "feel-good" clap-and-bounce track, in which Jackson relates a car crash to falling in love.

[22] "So Much Betta" samples "Daftendirekt" (1997) by Daft Punk and sees Jackson "tired of being number two" and trying to prove a man she's better for him than her rival.

[26] The album closes with "Curtains", an R&B song which sees Jackson putting on a show for her lover in the form of foreplay and filming it.

[30][31][32] Jackson promoted the album through televised performances on Good Morning America,[33] The Ellen DeGeneres Show and MTV's Total Request Live.

Her performance on Total Request Live was her first MTV appearance in six years, following her being blacklisted by the network due to the Super Bowl halftime show incident in 2004.

[39] Later, Jackson performed "Luv" in a medley with "Rhythm Nation" on the ABC special America United: In Support of Our Troops on September 7.

[40] Although the album promotion stopped in June, Jackson's fifth concert tour—the North American Rock Witchu Tour, with the support of Live Nation—began on September 10, 2008.

[41] Amy O'Brian of The Vancouver Sun described Jackson's stage show at the GM Place as a "high-voltage performance".

[42] According to O'Brian, "[w]ith an ear-piercing blast of pyrotechnics, a fog of thick cloud and dancers that popped up out of the stage and runway, Jackson proved within the first minutes that she didn't choose the low-budget route for her Rock Witchu Tour.

"[42] Similarly, Jim Harrington of The Oakland Tribune offered a positive review, stating: "Like Jackson's previous tours, 'Rock Witchu' was a flashy, high-budget extravaganza built on well-choreographed dance routines and plenty of theatrics.

[46][47] On November 19, it was announced that Jackson would bring the tour to Japan for a series of five shows in Saitama, Nagoya, Osaka, and Fukuoka in February 2009, but all five dates were canceled.

[52] Due to a rushed release and no international promotion, the song failed to chart highly in European countries, peaking at number thirty-six in France[53] and thirty-two in Ireland, but reaching the top five in Greece.

[65] Music critic Keith Harris of Rolling Stone wrote, "Janet Jackson has abandoned the plastic R&B of 2006's 20 Y.O.

for a sexier brand of digitized megapop [...] you can dismiss any images of the abusive Jackson clan that flit into your mind.

[4] Sal Cinquemani of Slant Magazine described it as Jackson's "most cohesive album in a while", giving three-out-of-five stars.

Music UK gave it seven out of ten stars saying "Still, if not perfect, there's plenty to like on Discipline, and while none of it is exactly vintage Janet, there's enough here to keep the Jackson name on pop's A-list for a little while longer.

"[66] Carol Cooper of The Village Voice called Discipline "the most cohesive deep-groove album from La Jackson since Control.

"[60] The Boston Globe music critic Joan Anderman criticized the album, saying "Jackson's decision to recycle the nympho routine one more time is just boring [...] A quarter century into her career, it was Jackson's moment to take a breath, dig a little deeper, and make a bold - or at least a different - statement.

"[61] Entertainment Weekly's Margeaux Watson wrote that Jackson's lyrics "sound like the cheesy text messages of a lovesick adolescent" and gave a C− rating.

[57] Nick Levine of Digital Spy wrote that "Jackson's attempts to play the uber-nympho are beginning to sound very, very desperate" with "embarrassingly lewd lyrics" and gave the record 2 out of 5 stars.

[93] On September 22, 2008—while on the Live Nation-supported tour of North America—Jackson parted company with her recording label Island; their 14-month relationship was dissolved per a request by Jackson.

[94] The singer had previously expressed dissatisfaction with the label, first telling SOHH.com that they "stopped all promotion whatsoever on the album" after releasing the first single, "Feedback".

Always known to break new ground and set trends, Janet's departure from Island Records makes her one of the first superstar artists to have the individual freedom to promote their work through a variety of avenues such as iTunes, mobile carriers and other diverse and innovative channels".

I will probably continue to do music – and acting is still a strong passion of mine – but I really have been loving behind-the-scenes work: producing, directing and all the technical stuff".
