セガ・ミュージック 第一音楽出版事業部 (Sega Music, First - Music Publishing Division)

You know... now that I think about it some more... I'm not actually sure if "第一音楽出版事業部" is actually a part of the name, or if it's just a descriptive label in the JASRAC database which should actually be stored in a separate database column from the name itself... but isn't.
