“…This article is not concerned with the validity, well-posedness, value, usefulness, or applicability of MGR; or whether MGR is "replaced by," or used in the service of, e.g., music similarity, autotagging, or the like. It is not concerned with making general conclusions about or criticisms of MGR or evaluation in MGR, which are comprehensively addressed in other works, e.g., [1,83,84,[105][106][107][108][109]. Finally, it is not concerned with how, or even whether it is possible, to create faultless datasets for MGR, music similarity, autotagging, and the like.…”
