AMG
Let me spell something out for one problematic user. This user claims that "not to use AMG to source genres, as they list overall genres for an artist, not an indivitual work". This statement would be true  if the genres listed on Artist's page were identical to the listed genres on this album, which obviously are not. Do all albums list the same genres as the disputer claims? The answer is obvious, hope the user  finds out. I hope the disputer will consider that his opinion is not a fact but a baseless claim and even "Any user using them should be trout slapped even when explained." can't be considered as a serious argument but a hateful claim of a person with prejudice against this particular website.
