23.122.217.39 wrote:"Queen of the Glass" is likely the meaning he intended rather than "The Queen Made of Glass", and that's a perfectly valid translation of グラスの王女. グラス is glass the drinking vessel while ガラス is glass the material. I don't know if he's referring to the drinking glass or glass the material, but the Japanese words suggest the latter, while the English song title gives me the impression of the former.
