I see that it is off-topic to ask a question about identifying a "song".
and it is not about...
identifying a song, genre, instrument, etc.
Where could one ask such a question?
Particularly in this day-and-age of horrible music meta-data, where listeners no longer get liner notes or physical packaging, it can be a mystery as to what piece/composer a track is. Is there an existing stack exchange site where one can ask this question? Should we consider allowing it on Musical Practice & Performance?
The piece I wanted to ask about is this (just to give an example)
First track on "Gregorian Chant: The Definitive Collection" by "Benedictine Monks of Santo Domingo de Silos" Track Title "Mass Of The Angels - Kyrie VIII Mode V" Who is the composer? Approximate year?
