SEVENTEEN begins their Thunder comeback with their most ambitious album to date, featuring 16 tracks including 13 solo songs and powerful group numbers. The title track “Thunder” symbolizes each member’s transformation, while global artists like Pharrell Williams and Timbaland strengthen the production. From unique teasers to a grand live showcase, SEVENTEEN celebrates a decade of growth and creative energy.
SEVENTEEN Comeback Begins with Thunder and Their Most Ambitious Album Yet
SEVENTEEN announces a dynamic comeback with the new title track “Thunder.” On May 13 at 10 PM, they revealed the tracklist for their fifth full-length album HAPPY BURSTDAY through the official team SNS. This album features 16 tracks in total—three group songs and 13 solo tracks, one for each member. It includes the highest number of new songs ever released in a SEVENTEEN album.
Thunder Symbolizes SEVENTEEN Identity and Comeback Vision after 10 Years
The title track “Thunder” compares each member’s growth and reinvention to thunder and lightning. It symbolizes their determination to expand their individual worlds. The song was written and composed by core SEVENTEEN producers Woozi and BUMZU, with S.COUPS also credited as a composer. This musical approach reflects their evolution after 10 years in the industry.
13 Solo Tracks and Global Talent Expand the Thunder Comeback of SEVENTEEN
The opening track “HBD” is short for “Happy Birthday.” It captures the intense celebratory energy of SEVENTEEN’s 10th anniversary and symbolic rebirth. Another group song, “Bad Influence,” stands out with an impressive production team. Global artist and producer Pharrell Williams, a 13-time Grammy winner, handled its writing, composition, and production. The solo tracks are also gaining attention. For the first time, SEVENTEEN included individual songs from all 13 members in a single album. Titles like THE 8’s “Skyfall,” Joshua’s “Fortunate Change,” and Wonwoo’s “99.9%” reflect their unique styles. Other solo tracks include Seungkwan’s “Raindrops,” Hoshi’s “Damage (feat. Timbaland),” Mingyu’s “Shake It Off,” and DK’s “Happy Virus.” Woozi’s “Destiny,” Vernon’s “Shining Star,” Jun’s “Gemini,” Dino’s “Trigger,” Jeonghan’s “Chance,” and S.COUPS’s “Jungle” also highlight the individuality of each member.
SEVENTEEN Comeback Album Gains Strength from Thunder-Level Production Team
Hitmakers Woozi and BUMZU once again led SEVENTEEN’s creative process. All members actively contributed to songwriting and composition, which raised the album’s quality. Top global names like Pharrell Williams and Timbaland, known for working with Madonna, Mariah Carey, and Sam Smith, joined the production. They were supported by producers such as Pdogg, VINCENZO, EL CAPITXN, and singer-songwriter Ha Hyunsang. Together, this team crafted an album that lives up to SEVENTEEN’s 10-year legacy.
Tracklist Video Sparks Curiosity Ahead of Thunder Comeback
The tracklist video adopts the point of view of a CARAT (fan) invited to a rebirth party. The viewer enters a phone booth just outside the party location and discovers stickers showing each song title. The eerie mood, with lightning ready to strike at any moment, hints at the intense story SEVENTEEN plans to unveil. This creative presentation adds depth and excitement to the album’s concept.
SEVENTEEN Comeback Stage and Album Title Build Anticipation for Thunder Release
The album title HAPPY BURSTDAY combines “Birthday” with the word “Burst,” which means explosion or sudden release. This unique name reflects the idea of SEVENTEEN exploding with new potential and energy. To heighten the excitement before the May 26 album release, SEVENTEEN will hold a special event called the BURST Stage. This comeback showcase will take place on Seoul’s Jamsu Bridge on May 25, one day before the album drops. It aims to amplify the comeback mood to its highest point.
Online Communities Enjoy an Accidental Preview
On the afternoon of May 13, a user on the Korean forum theqoo posted about seeing a bus wrapped with a “Thunder” advertisement. This happened before the track had been officially announced. The user felt surprised but chose not to upload the photo until after the official reveal. Other forum users guessed the bus had mistakenly started running a day early. They found the situation amusing and praised the original poster for waiting until the right time to share the image. A small error from HYBE LABELS turned into a fun episode among the fans.
