Singer-songwriter IU is set to release her emotionally charged new single "Unknown Planet."

The digital single, dropping on various music platforms at 6:00 p.m. (KST) on Thursday, features two title tracks: "Unknown Planet" and "Dear My Crazy Soulmate." Both songs showcase IU's lyrical prowess, with the artist penning deeply personal and evocative verses.

This release marks IU's first new material in a year, following her September 2022 hit "Bye, Summer." The single is generating significant buzz among fans and K-pop enthusiasts alike, as it offers a tantalizing preview of IU's highly anticipated sixth studio album.

The music videos for both tracks are set for a staggered release. The cinematic visual for "Dear My Crazy Soulmate," featuring veteran actors Kim Young Ok and Shim Dal Gi, will debut on Thursday to coincide with the single's release. Fans can look forward to the dreamlike music video for "Unknown Planet" on September 16.

Industry insiders are particularly intrigued by this release, as it's IU's first musical offering since her widely publicized split from actor Lee Jong Suk in July. While it's unclear whether the lyrics directly address her personal experiences, many speculate that the breakup has influenced her artistic expression, potentially showcasing a more mature and nuanced emotional depth.

The production team behind the new tracks is equally noteworthy. "Unknown Planet" boasts collaborations with rising artist Kkum and acclaimed producer Sumin. Kkum, known for his emotive compositions, previously worked with IU on her remake of "October 4th." This time, he's taken on both composition and arrangement duties for "Unknown Planet," leaving fans eager to hear the results of this creative partnership.

Sumin, a multifaceted talent in the Korean music scene, brings his production expertise to the table once again. Having previously arranged "Last Scene" from IU's "A Flower Bookmark 3" and composed "Epilogue," Sumin's involvement in "Unknown Planet" further cements his creative relationship with the artist. His reputation for crafting cutting-edge sounds has industry watchers excited about this latest collaboration.

"Dear My Crazy Soulmate" takes IU in a different direction, featuring work from an international songwriting team. Given IU's past success in interpreting foreign-penned tracks like "Flu" and "Celebrity," expectations are high for this cross-cultural musical experiment.
