Suno's Prompt Jukebox Achieves Milestone of 500 Artists

In less than one month since its official launch on May 7, 2026, Suno's artist prompt dictionary, titled "Prompt Jukebox," has successfully surpassed 500 artists. Developed by Spollup Co., headquartered in Chofu, Tokyo, this web-based service is designed specifically for Japanese-speaking users of the AI music generation platform, Suno.

Overview of the Service

The Prompt Jukebox is a dictionary-type web service that generates and allows users to copy prompts necessary for creating targeted sounds using Suno. Its design philosophy centers on being a platform "created by Japanese, for Japanese, and for the enjoyment of Japanese users," emphasizing the importance of a Japanese user interface (UI) and familiarity with the artists included in its database. Prominent artists from genres including J-Pop, enka, and popular international rock and pop have been carefully selected to ensure that fans feel a deep connection to the music prompts available. Users can paste prompts with just one click, making the process both quick and user-friendly.

Significance of Surpassing 500 Artists

When the service launched on May 7, the database comprised 300 artists. In a short time, the program has expanded by an impressive 200 additional artists, fulfilling a key milestone in Spollup's roadmap, which aims to reach 1,000 artists by June, 3,500 by August, and ultimately 10,000 by December. While extensive prompt dictionaries have already established a foothold in English-speaking markets, there has been a notable gap in services tailored to Japanese listeners. Prompt Jukebox aims to fill this gap by providing high-quality collections that resonate with familiar artists in Japan, positioning itself as the preferred choice in the local market.

Functional Updates: Innovative Navigation Features

Following the addition of the 500th artist, enhancements to service functionality are continuously in development. One such feature is the "Similar Artist Navigation," allowing users to transition seamlessly to musicians with similar musical styles with just one click. In scenarios where users click on an artist not in the dictionary, the system ensures a smooth transition that retains the artist’s name in the search field, referring users to a request form to suggest additional artists they would like to see added. This interactive approach encourages user participation in the ongoing expansion from 500 to 10,000 artists.

Feature Highlights

Pricing Structure

All artist prompts are entirely free (both viewing and copying). Lyrics generation is free up to three times a month; for unlimited access, users can subscribe to the Premium plan for 500 yen monthly. Premium subscribers will also receive prompt revision suggestions and contributor badges over time.

Ten Thousand Artists Roadmap

Ongoing Quality Improvements

The prompts for the 500 artists will continue to be refined in response to changes in Suno's specifications and user feedback. Structured data regarding artist names, musical styles, moods, and other attributes will be progressively enhanced beyond the initial launch phase.

Prompt Jukebox is developed and operated by Spollup with a cohesive team comprised of internal engineers, marketers, designers, and various contracted experts, including composers and SEO specialists.
