Context is everything. Stan or stanning is a term that came out of a song by Rapper Eminem call Stan which is about an obsessed fan. That term is now used to describe ones self or others who are dedicated fans.   IU is obsessed with treating her fans well, so this song is a tribute song to her fans.

The song Shopper is actually an continuation of the story IU started with her song Holssi. Again context is everything when trying to understand IU Song's.  W/o going into great detail, she had considered retiring from singing after her 2022 Golden Hour Concert. There were several reasons she considered it, but after the reception she got at the Golden Hour Concert, where she became the 1st female performer to headline a concert at the Olympic Stadium in Seoul, she decided to do something that Kpop soloist NEVER DO. and that is to break into the Western music concerts.  The only kpop soloist to have held concerts in the US have been members of big groups, like BTS and BlackPink, where certain certain individuals have gain a following in the West based of their groups popularity. And virtually all of them spoken English very fluently.  

So Holssi was her Declaration that she was going to see how high she can go. Holssi meaning Dandylion seed. Her MV's for Holsdi and Shopper were both filmed in the US which gave everyone a clue as to what she is aiming for.  Where Holssi is her Declaration to see how far she can go, Shopper is her statement to her fans to be all they can be.  Context here requires a little undersranding of Korean culture.   In Korean society the word greed is commonly used to mean that someone is using their ambition, talents, skills and dreams to achieve too much. People are often encouraged to settle for less than they are capable of.  IU is challenging those ideas. In Shopper she is encouraging everyone to be all they can be. Enough is never enough, meaning  if you can do better do better.   She also talks about Victory, which means to set your sites on your goal and go for it. That therebis no plan B so success is the only option.

IU songs are rarely simply about what they seem to beat first glance. IU MV's are helpful in this regard as IU uses her MV's to add depth and meaning to the story she is telling. That said her MV's can be a challenge to decode especially if you don't know any of the background.  Everything in an IU MV has meaning and is there for a specific purpose, which makes decoding her songs within the MV and real study in lyric writing and composition.

So the comment about Shopper being odd or strange etc is understandable because you haven't watched the MV or know of any of the other background information about the song.

The light sticks are a kpop thing. Each group/soloist have their own.

Love Wins All needs the context of the MV.  At the end of the song  it was a wedding dress. The red is from the ending of the of the MV where IU and V are taken by invading Cubes and all that is left is their clothing. The Cube turns red as it destroys them.

Shh.. is about mother daughter relationships. The pictures are generations of Korean female singers.

I saw her in Atlanta. All of her 6 concerts in the US were sold out in 15 minutes.  There is no one like her.

Other facts about IU
1- she debuted at 15 in 2008
2-she started to audition at 13 and was rejected 20 times b4 being signed and debuted in 10 months. Most other KPOP acts train for years before debuting.
3- she has more #1 hits songs than any other group or soloist by a factor of 3 (currently 35).
4- in January of 2023 Rolling Stone Mag added her to their list of the 200 Greatest Singers of All Time.

IU pays tribute to women in the industry from different generations in her performance of her song s.h.h.

A song made by women for women.

In it she talks about how women relate to each other, the high price of being a woman, what love is like between women and the relationship between mother and daughter.

It is also a recognition of how difficult the K-pop industry is for women.

Surprisingly, IU is the only soloist and female artist to perform in stadiums in Korea.
Because not even the biggest female groups of all generations in K-pop were allowed to perform there, they are only offered to men and male groups.
The only soloist to have 100 concerts.

The Korean industry looks down on women, they limit them to performing in small venues, they do not allow them to grow and that is why they retire before consolidating their careers.

IU is paying tribute to the older female artists who inspired her, to the younger ones who are now paying homage to her... this goes beyond statistics and status, but is a celebration of artistic legacy and the emotional bond that unites different generations of artists.

IU has a lot of fun performing, that’s why she’s , really really good ❤

You can find out what the red lights and the last dress mean by watching the Love Wins All music video.😊

I'm not sure that I've ever before encountered someone whose talent is as diverse as that of IU. I first knew her from her acting in "My Mister", and I'm glad I saw that before thinking of her as a star. As an actress, her performances are diverse, and she emotes so well in dramas and videos. As a singer, her tone is great and so much power seems to flow effortlessly out of such a small human. For a solo artist in a K-Pop world dominated by groups, she is able to entertain even when alone on stage. Her lyrics tell such stories, although I'm sure I miss a lot by not knowing Korean. She's not a model per se, but it seems that she's a chameleon, so that stylists can make her up to be different people, and that's who she becomes. Finally, she's comfortable on variety shows as both a guest and a host, and is able to interact comfortably with others and make them comfortable as well. To top it off, she seems to be a truly good person.

No dais una  , IU , es única , ella  compone sus canciones y las produce , no se parece a nadie , es la mejor solista que hay en Corea

❤❤❤ thanks for reacting to more than IU.

I was going to comment about it but you actually figured it out at the end =))
IU is known for her high quality/production concerts and her long encores- she basically does encores and en-encores lasting hours- so this time she actually outdone herself by organising an entire concert as an encore for her first world tour

The first song is “ I STAN U “ from her seoul comcert ( 4 different days ) and the song is fans song that IU’s wrote for her fans.

IU said that Shopper is about encouraging people to have dreams and ambitions, as society nowadays seems to make it so that even young folks  choose and hope for what is conventionally deemed safe or stable lifestyles and careers instead of following their actual wishes and taste
From what I understood there is a word that has both the meaning of "ambition" and "greed" so there is stuff lost in translations 😅

I recommend you watch more IU reaction videos! 💜

IU is a Korean superstar who can fill a large stadium with her fans...

Thank you for the IU reaction. very much appreciated.

아이유는 대한민국의 국보입니다

홀씨는 더이상 꽃이 아닌 홀씨로 살겠다는 아이유의 다짐이에요 어릴 때는 본인이 예쁜 꽃으로 필 줄 알았는데 지금은 홀씨처럼 자유롭게 떠다니며 살고 싶다고 하네요

Early IU (16 years ago) had a strong, clear voice. Later IU perfected the breathy feminine voice. Its a deliberate style choice. She was recently on a talk show explaining 'Its technical, let more air escape on this note'.

Thanks for react iu 💕

🥳❤️‍🔥👍+😊❤❤🎉

쇼퍼는 22년도에 아이유가 처음으로 스타디움 공연을 하고 나서 가수로서 더 큰 목표를 가지게 된 포부를 담은 곡이에요 그러면서 팬들의 꿈도 응원하는 응원가이기도 하죠
