History YMMV / IU

* PopCultureIsolation: She's a megastar in Korea but a non-entity in the West outside the K-pop community. It doesn't help that she only promotes in Asia.

* PopCultureIsolation: She's a megastar in Korea but a complete non-entity in the West outside the K-pop community (which makes her 2023 mention as one of only two Korean singers in ''Magazine/RollingStone'''s "[[https://www.rollingstone.com/music/music-lists/best-singers-all-time-1234642307/ 200 Best Singers of All Time"]] list more surprising). It doesn't help that she only promotes in Asia.

* SignatureSong: "Good Day", due to the immense success and popularity boost it brought her.

* PopCultureIsolation: She's a megastar in Korea but a complete non-entity in the West outside the K-pop community. It doesn't help that she has never toured outside of Asia.

* TestosteroneBrigade: Her voice and visuals have won her a lot of fanboys, including high-profile idols like Jungkook of Music/{{BTS}}.

* SugarWiki/MomentOfAwesome: Following her scandal with Music/SuperJunior Eunhyuk (see YokoOhNo), everyone mocked her for "trying too hard to stay relevant" and insisted that her career was over. Her next comeback "Modern Times" ''swept'' the charts and won her many music show awards.

* YokoOhNo: Both she and Super Junior member Eunhyuk got this treatment when a selca of the two (with IU in her pyjamas and Eunhyuk topless) at her home was "accidentally" posted to her twitter. Despite deleting it immediately, it spread quickly and brought her ''very'' angry [=ELFs=] on her back, while her own fans either hated on Eunhyuk or left her out of disgust. Her company's, uh, [[LameExcuse "visiting the sick"]] statement aside, details of this incident remain unknown. The last of this apparent couple came up in May of 2013 when there was a rumor of marriage, which both denied. The couple has been buried since then and the public has gotten over it, though cringeworthy hate from some [=ELFs=] still pop up occasionally.

* InternetBacklash: IU's "Chat-shire" album got into a huge controversy. In the Music Video for the title track, the lyrics mentions how she feels sometimes a child, sometimes an adult and emphasized this with the image of her sucking in a baby bottle. Since then, she has been accused of promoting pedophilia. To add more fire, the song "Zeze" became even more controversial because of the lyrics "climb up me" and soon she was accused of being a pedophile [[note]]Zeze is a children's book where the main character talks to a tree and the tree tells him "Climb up me" so IU is directly referencing this scene[[/note]]. Finally, she was accused of being a Lolita and starting a trend in K-pop [[note]]in reality the so-called "Lolita concepts" i.e. dressing in a cutesy childish way, have been part of K-pop since the first idol group[[/note]]. On a side note, someone researched the IP's of the people who comment against IU in Korea, it turned out to be only [[https://twitter.com/ikonOT7/status/663388216343396352?ref_src=twsrc%5Etfw a dedicated minority]].

* FunnyMoments:
** The grunt heard in "You and I"? That was IU. Yes. And it wasn't a ThrowItIn either - [[http://www.google.com.au/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&cad=rja&uact=8&ved=0CCoQFjAB&url=http%3A%2F%2Fweheartiu.com%2Fforums%2Fthreads%2F120111-the-truth-behind-the-grunt-in-ius-title-track-you-and-i.4968%2F&ei=4o2iVOfMCKW7mQXOwoKQCA&usg=AFQjCNFJPGalTB3q4i-aSgDti1dPzNf36w&sig2=wgH_0NC8Chqc8R7MZiPlBg the producer specifically wanted her to do it]].
** Her appearance on "Weekly Idol" when she did the "Random Dance Play" segment - and ''another'' artist's song (Sunmi's "24 Hours") came on. And yet she still attempted to dance it.

* FandomRivalry: Brief one when Music/{{Juniel}} first debuted since her company decided to really go with the mediaplay of her being "the next IU" since both have similar voices and play guitar. Some IU fans were quick to dismiss Juniel lacked the vocal technique IU had, while some Juniel fans looked down on IU for not being "a real artist" like Juniel who writes her own songs. Comparisons are no longer made so both fandoms have moved on.

* YokoOhNo: Thankfully averted. In May of 2013, there was a rumor of her marriage with Music/SuperJunior member Eunhyuk. They both denied this.
