“So too with music. Halacha dictates that we should not make weddings not cut hair and refrain from things that cause us enjoyment and make us happy.”
You mean “and refrain from things that cause us” …to dance with gusto; as opposed to repeatedly putting one foot in front of the other.
Today, we lead such miserable nervous lives and many need music to alleviate misery and thereby enable them to come closer to Hashem because you can’t serve Hashem without being happy ..Ivdu es hashem b’simcha.
