Acclaimed Flop: Credited as having one of the strongest, loudest, biggest voices of her generation and being extremely original in her attitude to her work. Regardless, Bionic and Lotus weren't that successful. She sticks with pleasing her fanbase now.
Alternative Character Interpretation: She doesn't like touring or recording and that's why she only releases albums every four years and last toured in 2008. She does love her The Voice gig and prefers to focus on her kid and boyfriend.
Fridge Brilliance: Due to an unsteady and unhappy childhood, she decided to make her family her top priority, thus the lack of desire to tour or promote her music but enjoying a steady gig on The Voice because that only requires a minimal amount of promotion and traveling.
Banned in China: The music video for "Dirrty" was censored in Thailand due to Thai-language posters that advertised its sex tourism (including mention of child prostitutes). *
It also caused controversy in America for its sleazy content, but it wasn't banned for it.
Broken Base: Most musical fans love her first three albums (self titled, Stripped, Back To Basics), but after 2008 there is a shattering of her fan and former fan base. Some prefer her pre 2008 self, others like the recent career and artistic decisions she has made.
Stripped was pretty divisive as some fans of her first album thought going the Britney-fanservice route was a disservice to her calling card, that she could actually sing, pretty damn well.
Call Back: "Lotus" features a lot of lyrical and musical call backs to her earlier works:"Reflection" gets a shout out in the introduction, "I won't let you bring me down" in Best Of Me reminding people of Beautiful, "I'm A Fighter" in Army Of Me, pretty self explanatory, "Voulez-vous coucher avec moi ce soir?." in Around The World, reminds people of Lady Marmalade, "Red Hot Kinda Love" refers to Infatuation on Stripped. "Let There Be Love" reminds many of her works on "Bionic".
Career Resurrection: "Stripped" and "Back To Basics" were both peaks in her interest and adoration worldwide.
Creator Backlash: "Bionic" has all but been forgotten, a half-assed second single, tour cancelled, her claiming she'd done all the work recording the album and didn't regret not touring for it. Doubts are for any song on it making to her next era.
Lotus received even more backlash from Christina than Bionic. Almost the entire promotion for the entire album consisted of a video for Your Body, three performances on The Voice and a few interviews (which mainly focused on The Voice). Your Body was very well received but she never performed it live and Just a Fool was announced and released as the second single with almost no promotion. The final nail in the Lotus era was that while at first she claimed to have taken a break from The Voice to tour those plans were either scrapped or Blatant Lies. Some fans believe this was the result of Executive Meddling while others believe this is simply the result of the album flopping.
Creator Breakdown: I'm OK and Oh Mother are about the abuse she witnessed as a very young child. She has also admitted to suffering depression partially due to this experience. This shows in the songs Understand, Mercy On Me, The Right Man and the greater Stripped album.
Development Hell: Invoked by Christina herself in choosing to take a couple of years off (At least three) between each album, starting from 2002 to 2010. To some people it's annoying and leads to disappointment, other people think she's justified in her choice to take a break. Lotus was an aversion of this expected trope, taking only 2 years and 6 months to come out. She's now pregnant and engaged so the album is due in 2017 according to fan guesses.
Executive Meddling: Happened to Bionic, backed up by her collaborators as far as song choices are concerned.
Some fans believe this is what happened to Lotus. Christina was supposedly forced to release before she was done working on it to capitalize on the popularity she got from The Voice and because of this she abandoned the album.
Music Is Politics: When she started she was the louder Britney Spears. Then she got sexy and strong with Stripped, then classier and sweeter with Back To Basics, and since 2008 she's been trying to appeal to Lady Gaga's art pop demographic. She used to fill a niche but now since Lady Gaga happened, she's been demoted to a degree. There are only so many roles in the pop landscape.
Signature Song: "Beautiful" has penetrated social consciences and plays a part in most inspiring shows, performances, and is covered frequently. "Genie In A Bottle" also has great radio play even now.
What Could Have Been: Bionic was going to have songs written by Goldfrapp, but none of their songs were completed. She also could've gotten Bionic out earlier and prevented the Lady Gaga backlash. There are alot of wasted moments in her career, across the board from music to touring to collabs to friendships to movies.
