well, it's probably not practical to directly say that music has the function of cleaner blood and healthier body. Personally, I think that good music can completely calm you down, relax your body and mind, and make your body healthier, because it has long been recognized by medicine that mood directly affects your body.

this really depends on your personal preference. I like light music, but some people have no feelings about light music. Pop music can make them feel happier and more excited, and even have a feeling of excitement. So, as long as it produces a sense of pleasure, pop music is music that is good for your health. If you like the elegance and quietness of light music, and can fully relax your body and mind, then light music is music that is good for your physical and mental health. This depends on your personal music preference. If you listen comfortably, your body will have a good reaction and naturally be healthier.

If you also like light music, you can continue to communicate ~:) I can recommend some good tracks to you ...
