The album's lyrical content, composing and arrangement was handled by multiple music collaborators, such as Nao'ymt, Sugi-V, Michico, Tricky Stewart, T.Kura, among many others.

For Queen of Hip-Pop, Amuro's record label Avex Trax hired a wide array of musicians, such as Michico, T.Kura, Sugi-V, Nao'ymt, among many others to work on the album.

The song "WoWa" (pronounced "Ooh Wah") is an uptempo R&B and dance-pop number with an arrangement that mixes sounds made by real people, such as marching, hand claps, and flutes.

[4] "Free" is a mid-tempo Southern hip hop tune with a dark intro that develops into a bewitching, rhythmic synth sound.

[4] "No" is a club tune with a bouncy sound; the middle eight, with its handclaps and synths, stirs up calls of "N-A-M-I-E."[4] A hidden track known to fans as "No pt.II" is included shortly after "No"; it is a remixed slow-paced version of the song containing new vocals.

[6] A licensing deal was struck with MGM studios allowing Amuro to freely use the character in her album artwork and promotion.

[1] During an interview with Bounce Magazine in July 2005, Amuro stated that the usage of the word "Hip-Pop" in the album title was to give the listener an easy-to-understand image of the record; she explained in full detail; It was the same with "Style," but I wanted the album title to express the image of the work in a single word that would be easy to understand.

She performed "Alarm" at the 2004 MTV Video Music Awards Japan held at Tokyo Bay NK Hall on May 23, 2004.

[13] "All for You" has been certified gold for shipments of over 100,000 by the Recording Industry Association of Japan (RIAJ)[14] and reached number six on the Oricon Singles Chart.

[17] Interestingly, when the album was released only "Girl Talk" was included in the tracklist while, "The Speed Star" was omitted for unknown reasons.

"[18][19][20] The success of "Girl Talk/The Speed Star" earned Amuro an invite to perform at the 55th NHK Kohaku Utagassen, but she declined.

[25] In March 2005, a month before its official release, Amuro sung the song at Japan's largest fashion event, Kobe Collection.

[31] The video was predominately filmed in black-and-white and depicts Amuro and her backup dancers dancing in a warehouse wearing biker fashion.

There are also interspersed scenes throughout the video of a TV screen in a bar showing Amuro walking down a runway while wearing a yellow minidress.

At the end of the video, a ring is chucked at the screen and picked up by a long-haired man whose look is reminiscent of Amuro’s ex-husband.

The music video for "All For You" was directed by Masashi Mutō[32] and depicts Amuro singing emotionally all alone on a beach in Tateyama City, Chiba Prefecture in front of a sunset.

The music video for "The Speed Star" was also directed by Ugichin;[34] it features Amuro and five background dancers performing in front of a giant car motor.

[35] Filmed in an undisclosed studio, it features Amuro and several dancers of various ethnic backgrounds dancing vehemently in a flooded room.

[37] To promote Queen of Hip-Pop, approximately 150 Namie Panther flags were displayed around Center Gai in Shibuya.

Five days after the release of Queen of Hip-Pop, a secret event titled “HMV 15th Anniversary Presents Namie Amuro "Queen of Hip-Pop"” was held on a special stage on the rooftop of Aqua City Odaiba, where she performed three songs from the album, including "WoWa," in the heat of over 30°C.

[52] At the end of the review he stated: "Oh, but then there are bouncy beats, apocalyptic dance-me-ups and crazy stop-starts sprinkled all over the record, as well as a few Engrish lyrics to laugh at.

[53] Tetsuo Hiraga of Hot Express was extremely positive on the album, feeling that, in his own words: "the songs are uncompromising and unreserved, and give the impression of the “real thing” that Namie Amuro wanted to make her own.

[4] In Japan, Queen of Hip-Pop debuted at the runner-up spot on the Oricon Albums Chart with 201,524 units sold in its first week, being blocked from number one by Ketsumeishi's Ketsunopolis 4.

[59][60] Queen of Hip-Pop was certified double platinum by the Recording Industry Association of Japan (RIAJ) for shipments of 500,000 units.
