How to tell if it is light music?

Light music should be defined as a relatively popular school between classical music and pop music. It can adapt some classical music, play some pop music lightly, and even describe a folk song in an artistic way. It doesn't need to be pure music, but it should give people a "light" feeling.

Pure music is a big category, including all music without human voice, and classical music belongs to pure music.

Pure music is music without lyrics in the original intention of composition. As pure music, this music mode expresses the author's feelings completely with pure and beautiful music, so it is generally called pure music.

The pure music of Bandari and Mystery Garden is very nice.
