いつだって僕らの恋は10センチだった。 オリジナルサウンドトラック vol.1

Utaite refers to amateur and semi‑professional online singers who post cover versions of songs—especially Vocaloid, anime, and contemporary J‑Pop/J‑Rock—usually under a pseudonym. The Japanese term literally means “singer,” but within online culture it specifically denotes cover artists active on platforms such as Niconico (Nico Nico Douga) and YouTube. Utaite typically collaborate with a small creative circle (arrangers/producers, “mixers,” video editors, and illustrators) to re‑imagine existing songs with new keys, fresh arrangements, stacked harmonies, and distinctive vocal color. The scene is closely tied to otaku and dōjin communities and thrives on anonymity, fan feedback, frequent uploads, and highly stylized online personas.

J-pop (Japanese pop) is a broad umbrella for mainstream Japanese popular music that blends Western pop/rock, dance, and R&B with distinctly Japanese songwriting, vocal delivery, and industry practices. It is characterized by strong hooks, polished production, bright synths and guitars, frequent key changes and modulatory bridges, and chorus-first or chorus-centric structures. J-pop spans idol groups, singer-songwriters, band-oriented pop-rock, electronic dance-pop, and R&B ballads, while remaining closely tied to television, advertising, video games, and anime tie-ins (anisong).
