Precautions:

The concept of background music is to distinguish between music with words and music without words when seductive plots appear in film and television works, rather than saying that music with words is "miscellaneous". After all, vocal music is also a form of music.

When there are seductive plots in film and television works, the translation of the name "background music" is based on the habits of Chinese people. To be exact, it is best to translate it into "untitled music" or "absolute music", and there will be no ambiguity such as "miscellaneous songs".

Therefore, both "untitled music" without words and "untitled music" with words are called music. There is no distinction between pure music and miscellaneous music, and of course there is no real "pure music".
