It was an eventful Monday in the K-pop industry as four powerhouse acts simultaneously dropped new music, flooding the scene with fresh tracks and igniting excitement across fandoms.

They include Hoshi and Woozi of the phenomenal boy band SEVENTEEN, who debuted as a duo sub-unit with the single album "Beam."

The album is led by the single "96ers," while the other tracks are "Pinocchio," featuring singer-songwriter So!YoON! of band Se So Neon, and "Stupid Idiot."

As with most SEVENTEEN releases, all three tracks in "Beam" were co-composed by Woozi and his collaborator Bumzu, while Hoshi is also credited as a composer in the single and "Stupid Idiot."

Hoshi X Woozi is SEVENTEEN's third sub-unit following the quirky trio BSS (composed of Seungkwan, DK and Hoshi), and Jeonghan and Wonwoo's JxW.

Yeji, who leads the girl group ITZY, also made her solo debut with the extended play (EP) "Air," becoming the first member of her team to launch a solo career.

Along with the four-song EP, the 24-year-old idol, known for her dance skills and fierce stage presence, also released a video for the title track "Air."

Comebacks

Meanwhile, EXO member Xiumin made his comeback with his second EP "Interview X," marking his first album after moving to his bandmate Baekhyun's label INB100.

Composed of six tracks, "Interview X" is fronted by the UK garage track "Whee!".

Xiumin's comeback has been mired in controversy after One Hundred, the parent company of INB100, recently claimed that the singer was barred from appearing on Korean broadcaster KBS' "Music Bank."

INB100 alleged that KBS informed them Xiumin could not appear on programs featuring artists from his former agency SM Entertainment, echoing past accusations that SM blocked its former artists from TV appearances, according to reports.

KBS has reportedly denied the allegations, while SM Entertainment has yet to comment on the issue.

Seulgi of girl group Red Velvet also unveiled her second EP "Accidentally On Purpose," her first comeback since debuting as a soloist in 2022.

The EP includes six tracks, with "Baby, Not Baby" serving as the lead single. 

"It is about embracing the affection of a relationship but refusing to confine to a specific image and focusing on staying true to myself," Seulgi said of "Baby, Not Baby" in a subtitled YouTube livestream held an hour before the EP's release.

March is shaping up to be a star-studded month for K-pop releases. 

Last week, BTOB, Infinite, BTS' J-Hope, Blackpink's Jennie and Treasure unveiled new music, while SF9, NCT's Ten, Stray Kids, THE BOYZ, STAYC, Le Sserafim and NMIXX are gearing up for their comebacks later this month.
