King & Prince's 78 Hidden Songs Finally Hit Streaming

On May 23, 2026 — exactly eight years after their debut — Japanese idol duo King & Prince unlocked 78 previously unavailable songs across major streaming platforms at the stroke of midnight JST. The tracks, which include single coupling songs and album-only cuts that had never been available digitally, are now streamable on Spotify, mora, Rakuten Music, and Amazon Music. The release was coordinated across platforms: mora is offering lossless audio for the new additions, Spotify JP announced exclusive limited content on its Instagram account, and TikTok's official account launched a campaign encouraging fans to post using the newly available audio.

The simultaneous announcements from multiple official platform accounts helped the hashtag trend nationally within minutes of the midnight drop. Fan response was immediate and emotional. Members of the Tiara fandom — King & Prince's official fanbase — flooded X with celebratory posts, describing the moment as the culmination of eight years of memories.

Reactions ranged from tearful nostalgia to excited playlist-building, with many fans sharing which song they chose to listen to first. The Tiara fan channel also hosted a live radio-style broadcast playing the newly released tracks alongside 'STARRING,' giving fans a communal listening experience in real time. Beyond the catalog milestone, the release has sparked renewed interest in member Takahashi Kaito's songwriting work.

Fans are highlighting his compositions within the newly accessible library, calling on new listeners to explore his credits specifically.

What to watch next: Spotify JP has signaled exclusive limited content on its Instagram account tied to the anniversary. With TikTok also running a user-generated content campaign around the new audio, the catalog drop is likely to continue generating engagement well beyond the anniversary date itself.
