Your mileage may vary with this singer when it comes to these tropes:
- Broken Base: Quite a few times. There are the fans of her older K-Pop music who don't really care for her newer K-Pop material, and vice-versa; there are the fans of her K-Pop music who aren't fans of her J-Pop music, and vice-versa; there are fans who prefer her "Baby BoA" image to her more mature, grown-up image and vice-versa... and then there's her English-speaking album.
- Covered Up: Her cover of "Scream" for her English debut. No, it's not the song by Michael and Janet Jackson.
- Crowning Moment of Heartwarming: Korean fans will often send food to their idol when they begin the promotional cycles as they know that their faves are often worked to the bone with little time to eat or sleep in between performances. BoA in particular was looking very gaunt when promotions for Hurricane Venus began and her fans picked up on that, sending food and good wishes to both her and her staff on her debut performance of popular Korean music show Music Bank. If only most fans could be that supportive of their favorites.
- Crowning Music of Awesome: Quite a few of her songs. "Energetic" from her English album was pretty epic, and the entire Hurricane Venus album was kickass from start to finish. Her J-Pop album Identity also fits this trope as it featured a sound more akin to her recent electropop as opposed to the fluffier pop she usually is known for in Japan.
- Ear Worm: Her entire discography is pretty much one long, infectious earworm waiting to dig its way into your ear and stay there for days.
- Epic Riff: "Hurricane Venus," "Dangerous," "Let Me," "Eat You Up," and "Energetic," to name just a few.
- Fanon Discontinuity: A lot of fans have disowned her English-speaking album, for various reasons. Some say that it was too generic and sounded like everything else on the radio at that point while others can't get over BoA singing about sex.
- Les Yay: The album cover for Best & USA.
- Moe: It's why she's popular among males, aside from her music.
- Signature Song: "Girls On Top," "Valenti" and "Meri Kuri" are some of her best known hits.
- They Changed It, Now It Sucks: BoA came under a lot of fire with the release of her album My Name due to her attempt to mature her image and sound. Many fans commented that they disliked that her image was becoming Darker and Edgier and wanted her to remain "Little Baby BoA." Needless to say, she was not pleased and quickly told fans and critics alike that she wasn't going to stop growing up just to appease them.
- Tearjerker: "Implode." You can tell it's going to be a heartbreaking song without even knowing the words...but once you do know what she's singing about it gets worse. Anybody who's ever unwillingly lost someone they still loved, whether it be through a breakup or from death will be hard-pressed not to be in tears by the end of the song.
- What Do You Mean, It Wasn't Made on Drugs?: The video for "Hurricane Venus" features a feather-clad BoA entrapped in a cage while several men dressed in red-feathered jackets fly at her cage and seemingly attack it. Cut to the occasional non-sequitur dance segment and yeah, that's pretty much the vid. I don't get.
