Archive Panic: While 15 studio albums may not seem much, they're often over 70 minutes. Also, she has over 30 official bootlegs, and lots and lots of b-sides and covers. Good luck.
The long 'girrrrrrrrrrrrrrrrrrrrrrrl' in live performances of "Precious Things".
Toriphiles & ex-Toriphiles can agree that her first five albums and Scarlet's Walk fall under this trope. A smaller group would add her post–Night of Hunters work to the group as well. A devoted Toriphile would say that virtually everything she has done is this.
Broken Base: Tori's fanbase can be summed up as 1/2 devoted fans and 1/2 ex-fans who complain too much that Tori's not making depressing piano music anymore.
Crazy Is Cool: She's quite awesome, and quite mad, and these are codependent traits; She dresses up as different personas and plays two pianos while straddling the bench. She speaks of fairies and making love to 'the Wolf' in interviews. Delirium of Neil Gaiman's The Sandman (1989) is partially based on her in later volumes, though in the beginning she just happened to resemble the Anthropomorphic Personification of Crazy Is Cool.
Critical Dissonance: Boys for Pele was panned by critics, but it's considered one of her best albums by her fans.
Ensemble Dark Horse: Many of her B-sides are very popular with Toriphiles, especially "Cooling", "Sugar", and "Honey". "Cooling" even topped a poll of greatest Tori Amos songs. In other words, "Cooling" got more votes than all of Tori's other songs on this poll.
Epic Riff: "Professional Widow" (harpsichord), "Precious Things" (piano), and "Silent All These Years" (also piano).
Germans Love David Hasselhoff: Earlier in her career, Tori was much more successful in the UK than in the US. It's no accident that she divides her time between there and the U.S.
LGBT Fanbase: She's had one from the beginning, stemming from her early performances in gay bars and for working in a genre that has been LGBT-friendly from the get-go. Her brash persona and troubled personal life have also given her diva-like qualities that appeal to gay men. She's also claimed that straight men actively dislike her music for its emotional rawness.
Misattributed Song: No, "Kissing in the Rain" on the soundtrack for Great Expectations is neither written nor sung by Tori, though she did contribute to other songs in the film. This track is written by Patrick Doyle with vocals by Miriam Stockley.
Memetic Mutation: "Ugh, you were right... It's not subtle." Explanation One episode of Bob's Burgers memorably featured a No Celebrities Were Harmed parody of Amos named Tabitha Johansson singing a song called "Oil Spill", which is really a metaphor for her vagina; the quote is Bob Belcher's reaction when he realizes how unsubtle the metaphor really is. Fans eventually figured out that "Oil Spill" was a (hilariously spot-on) parody of a sexually charged performance of "Icicle" that Amos gave on The Tonight Show with Jay Leno in 1994. As soon as they figured out, the comment section of the video of the performance was bombarded with the quote.
Refrain from Assuming: Tori never released a song called "Starfucker". It's "Professional Widow".
Signature Song: "Cornflake Girl" is what the general public remembers her for, though "Spark" and "Caught a Lite Sneeze" are also relatively well-known.
Squick: What some people think her song "Raspberry Swirl" is about: having sex with a woman on her period. The "raspberry swirl" is a mixture of menstrual blood and semen. Although Tori confirmed that the song is about how she always got her friends' backs, but she probably invoked such imagery on purpose.
Surprisingly Improved Sequel: Y Kant Tori Read infamously flopped, and Tori's solo debut Little Earthquakes became a success. Some may say that Under the Pink is even better than Little Earthquakes.
What many fans thought about her 2005–2009 material. It's been joked amongst some fans that the quality of her music is directly tied to how angry Tori is, and she has mellowed out ever since the birth of her daughter.
The general reason why Boys For Pele brought about a critical backlash. In retrospect it's regarded as one of her best albums.
Vindicated by History: Boys For Pele. Critically panned when it was first released, it's now regarded as one of her greatest albums.
Started with Night of Hunters. She managed to unbreak some of her Broken Base and most of the unpleasable fans are enchanted by the album, with some naming it as one of her best albums ever.
This continued with Unrepentant Geraldines which (at the time) became her most critically-acclaimed album since Scarlet's Walk.
And then both Native Invader and Ocean to Ocean built on the streak with the latter album now considered her highest rated 21st Century album on Metacritic.
