These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way.

YMMV: BoA (Korea)
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 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.
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.
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.
