IU

From making music to acting on screen, IU can seemingly do it all — and she commands unparalleled love and support from K-pop fans and the broader Korean music community. Her generation-spanning popularity was on display in 2024, when she dominated the charts. Her single, “Love Wins All,” climbed to the No. 1 spot on Melon’s TOP100 chart just an hour after its Jan. 24 release, becoming the second song to achieve this feat since the platform’s chart reform. The massively successful track led the weekly chart for four consecutive weeks, topped February’s monthly chart and on iChart achieved 339 perfect all-kills (the term describes when a song simultaneously tops iChart’s real-time, daily and weekly components).

The achievements helped propel IU to becoming Korea’s representative for Billboard’s Global No. 1 artist series. “It’s a bit humbling, a bit surreal, and honestly, it feels really special,” she says of the recognition.

Her success extended to the road. Starting March 2, IU embarked on a 31-performance world tour that played shows in Japan, Europe and North America — and was attended by some half a million fans, a record for a Korean female solo artist. She followed four sold-out shows at Seoul’s KSPO Dome with a performance at Manila’s Philippine Arena, the world’s largest indoor venue, where she became the first Korean solo artist to headline.

On Sept. 21 and 22, IU held encore concerts at Seoul World Cup Stadium, becoming the first female artist to perform at the venue and drawing 107,000 attendees across two nights, which set the record for the largest concert engagement by a Korean solo artist and female artist in Korea.

What are the advantages and challenges of being a solo act in Korea’s music industry?

If I had to pick one challenge, it’s that there’s no one to share energy with onstage. Groups have distinct roles, which create a synergy that’s hard to replicate as a soloist. But on the flip side, I get to enjoy all the love and attention by myself. (Laughs.)

Many Korean artists are making waves on Billboard charts. In your opinion, what sets them apart?

There are countless strengths, but what stands out is how K-pop groups maintain their individuality while being deeply respected by their fans. As a K-pop listener myself, I see how each group’s unique identity is cherished and upheld, which makes them so special. Of course, the music is top-notch, but the visual elements and storytelling also define K-pop culture. For instance, the distinct characters and worlds that exist only onstage for groups are something I, as a soloist, sometimes envy. These unique traits captivate fans, offering an experience that engages the ears, eyes and heart. Ultimately, it’s this blend of individuality and fan support that makes Korean artists shine.

Do you have any plans to collaborate with global artists?

In the past, I received many amazing offers, but the idea of collaborating with artists who spoke different languages felt daunting. I turned down those opportunities then, but I don’t feel the same way anymore. Now, I’m much more open to the idea of working with global artists.

You’re known for having a strong bond with your fans. What do they mean to you?

Initially, most of my fans were older than me — big sisters, older brothers and even uncle fans. At the time, I was a young solo artist without a solid footing, so I often felt cared for and protected by them. As I entered my mid-20s, fans my age became the majority. They resonated with my lyrics and music as peers, and we built a mutual understanding and grew together. Now, I have many younger fans, and I find myself wanting to support, encourage and nurture them. I see UAENA [IU’s fandom] and myself as having a steady, balanced relationship where we constantly exchange the best of what we can offer each other.

Why do you think you have such cross-generational appeal?

Without meaning to downplay myself, I think I appear relatively ordinary and less distinctive in my looks and personality compared to other remarkable stars in Korea. This might make me seem more approachable and relatable. Plus, Korea is a country with a lot of warmth, and I believe the support I’ve received reflects appreciation for my consistent hard work. Still, it’s fascinating that even teens connect with me these days.

You’ve encountered fans all over the world. Are there any memorable moments from your performances abroad?

It’s hard to pick just one, but Auckland [New Zealand] comes to mind. Their unique way of cheering made the entire experience unforgettable. Another standout was Jakarta [Indonesia], where the audience sang along to every song from start to finish. That level of enthusiasm left a lasting impression on me.

You’re often credited for both your meticulousness and flexibility. How do you balance these seemingly contrasting traits?

I feel like I’m constantly at a crossroads. You could say I’m flexible, or, less flatteringly, that I’m good at justifying things. (Laughs.) I’m naturally stubborn and like to plan everything thoroughly, but I’ve learned that things rarely go perfectly. Over time, I’ve practiced being more adaptable, and in doing so, I’ve figured out how to protect my mental well-being.

Beyond music, you’ve made your mark as an actor. What’s in store for 2025?

The drama I filmed throughout 2023, When Life Gives You Tangerines, will premiere on Netflix in 2025. It’s a project filled with the cast and crew’s hard work, and I’m excited to promote it. I’ll also be filming a new drama with a completely different vibe — glamorous and fun. Although I’ll be focused on acting for most of 2025, I’ve already started working on new music, so fans won’t have to wait too long for something fresh.
