As I understand, I’m too lazy to look up the shulchan oruch, the minhag is not to eat meat and listen to music at the same time.
Whether this applies to some background music, as in a restaurant is debatable.
Music used to be something rare and not easily available, nowadays, to avoid thinking, everyone plugs in to some kind of mind filling music. It is so commonplace that it barely elevates one to a higher state of simcha.
