A Symphony of Voices: 100 Streamers Achieve Guinness World Record with JOYSOUND Karaoke Relay

“Karaoke JOYSOUND for STREAMER” Marks First Anniversary with Guinness World Record Achievement

In a remarkable display of online community and musical passion, “Karaoke JOYSOUND for STREAMER” recently celebrated its first anniversary by achieving a Guinness World Record. The event, titled “Challenge to be the World’s Best Singing Relay,” successfully concluded a 100-person karaoke singing stream relay, officially recognized as the “Most participants in a livestreamed karaoke relay event.”

To further ignite the spirit of challenge, JOYSOUND has announced its sponsorship for future official Guinness World Record attempts that aim to surpass this new benchmark. This initiative underscores a commitment to expanding the joy of karaoke and fostering a vibrant online music culture.

Empowering Streamers: The Vision Behind JOYSOUND’s Online Karaoke Service

“Karaoke JOYSOUND for STREAMER” was launched with the goal of broadening the expressive possibilities for live streamers and video creators, while also strengthening their connections with listeners. The service enables anyone to easily host karaoke sessions on popular platforms such as YouTube, Twitch, Niconico Douga, and OPENREC.tv, and has garnered significant support since its inception.

The “World’s Best Singing Relay”: A Monumental Digital Gathering

The anniversary event saw a diverse group of 100 participants come together for an epic “singing stream” (or “utawaku”) relay. Beginning on December 5th and continuing through December 6th, each participant streamed for 15-minute intervals on their respective YouTube channels, seamlessly passing the musical baton to the next. The event, a first for the service as an organizer, attracted over 400 applications, far exceeding initial expectations, and showcased the vast potential and versatility of online singing streams.

The individuality of each participant shone through in their song choices and engaging banter, creating an immersive experience for viewers. The entire relay is available for replay, offering a chance to relive the historic moments:
