The five-member male band V01D released their pre-release title track "ROCKROCK 樂樂" at noon on the 3rd. This song marks the official start of V01D's activities and, while superficially telling a love story, it also contains the members' determination.

"ROCKROCK 樂樂" is based on a bright and refreshing pop-punk sound, featuring an addictive bright-toned guitar riff, powerful drum performance, and lively 8-bit bass line. The lyrics convey the message, "No matter what pain comes, we will respond with a smile. That is our answer," expressing the will to maintain a positive attitude even in difficult times.

The song's structure includes lines like "Touch of dawn, like a broken dream Night / Highway drowned in light, crashing again... Our song is Bad decisions / Broken heart No permissions," which are simple yet evoke strong imagery and emotional immersion. The chorus melody is highly addictive and easy for anyone to sing along.

Despite its fast tempo, "ROCKROCK 樂樂" is composed to highlight the band's sectional dynamics. The song effectively conveys energy during live performances, balancing mass appeal with the band's unique sound.

V01D members Song Yuchan (drums), Jo Jooyeon (vocals), Jung Jiseop (guitar + vocals), Kevin Park (keyboard + vocals), and Shin Nosuke (bass) all participated in writing, composing, and arranging the song. Through the creation process, they demonstrated strong teamwork and included their commitment to future activities. The members exchanged ideas spontaneously during rehearsals, creating a natural and energetic atmosphere.

V01D aims to be the best team where music, visuals, and performance work together as a complete narrative. "ROCKROCK 樂樂," symbolizing their first step, will be released on various music platforms starting at 12 PM on the 3rd. This song reveals V01D's musical colors and raises anticipation for their future activities.
