Mastering in Los Angeles. Music and lyrics Many of the themes and musical styles of B'Day were inspired by Beyoncé's role in Dreamgirls. The plot of the film revolves around "The Dreams", a fictional 1960s group of three female singers who attempt success in the mainstream music industry with the help of their manager Curtis Taylor, Jr. (portrayed by Jamie Foxx). Beyoncé portrays Deena Jones, the lead singer of the group and the wife of Taylor, and is emotionally abused by him. Because of her role, Beyoncé was inspired to produce an album with an overriding theme of feminism and female empowerment. On the hidden track "Encore for the Fans", Beyoncé said: "Because I was so inspired by Deena, I wrote songs that were saying all the things I wish she would have said in the film." B'Day was influenced by a variety of American genres, and, like Dangerously in Love (2003), incorporated urban contemporary elements such as contemporary R&B and hip hop. Some songs showcase 1970s and 1980s styles, achieved through record sampling. "Suga Mama", which employs blues-guitar samples from Jake Wade and the Soul Searchers' "Searching for Soul", contains a 1970s funk and 1980s go-go-influenced melody. "Upgrade U" uses a sample from Betty Wright's 1968 song "Girls Can't Do What the Guys Do". "Resentment" used Curtis Mayfield's "Think" from the 1972 Super Fly soundtrack. "Déjà Vu" has 1970s influence, "Green Light" has a classic groove, and "Get Me Bodied" features twang, a musical style that originated from Texas. Beyoncé crafted most songs on B'Day through live instrumentation and diverse techniques. This is evident on "Déjà Vu", which utilizes bass guitar, conga, hi-hat, horns and the 808 drum; it also features rap vocals by Jay-Z. In an interview with MTV, Beyoncé said: "When I recorded 'Déjà Vu' [...] I knew that even before I started working on my album, I wanted to add live instruments to all of my songs..." Lyrically, the song details a woman being constantly reminded of a past lover, shown in the lines: "Is it because I'm missing you that I'm having déjà vu?" "Get Me Bodied" is a moderate R&B and bounce track, which displays influences of dance-pop, dancehall, and funk. Lyrically, it speaks about a female protagonist going out and dressing up suitably to leave a lasting impression and get what she's looking for. The third track "Suga Mama" is a moderate R&B
