Suno's Prompt-Jukebox Reaches 3,500 Artists

In a groundbreaking announcement, Spollup Co., based in Chofu, Tokyo, has revealed that its AI music generation service, SUNO, has achieved an impressive milestone: the prompt dictionary specifically designed for Japanese users, known as prompt-jukebox, now includes a staggering 3,500 artists. This remarkable achievement comes just four months after its official launch on May 7, 2026, where it started with an initial roster of 300 artists.

Swift Expansion

The rapid growth of the prompt-jukebox has been nothing short of extraordinary. In May, just weeks after its launch, the artist count reached 500, and by July, it had surpassed 2,000. Now, with the latest numbers confirmed as of August 31, 2026, prompt-jukebox has secured its position as the largest AI music prompt dictionary in Japan. This progress aligns perfectly with the roadmap released by Spollup on June 6, 2026, which outlined the commitment to reach 3,500 artists by August.

Establishing Dominance in the Market

To define its stature, prompt-jukebox is compared with other similar web services in the sphere of AI music prompts. According to extensive web searches and comparisons made by Spollup as of September 2026, prompt-jukebox stands unparalleled among competitors in Japan due to its extensive database of artists. This distinction underscores its role in revolutionizing how users engage with AI-generated music.
