Although most instances of the long "o" have been standardized (ō, ou, oo), there are more than a few songs that are written by Shouko Ohmori, as referenced here. "oh" is common in transcribing names, but is nonstandard. One article that does not use "oh" is this one (there may be others). I don't know if the official english transliteration of the album credits uses "Ohmori", but if not it should replaced by "ō" or similar.

Also, from Wikipedia: Hepburn romanization#Loanwords says that macrons are used for all five vowels when transcribing loanwords. This should include "Giita/Gīta".
