As Huang understands the situation, in both France and the US (where the Enigma CD was made), copyright laws are very strict about requiring the authorization of the performers for "recorded works" or publication. Unless Difag and others agreed, it can be said that the CD produced by the Maison des Cultures du Monde was unauthorized and thus unlawful.
據她的瞭解，不管是法國或美國（謎 CD 在美國出版）著作權法，對「錄音著作」，出版需有演唱人授權的規定均十分嚴格，若沒有里望等人的授權，巴黎世界文化之家的 CD 可說是不被允許出版的。
