There is a sentence in The Analects of Confucius that describes people who love or are good at music, and their moral character is not bad. That probably means something like this. Which sentence is it in the original text?

The so-called people who study or like music will not be bad learners are just fairy tales fabricated by contemporary people. There is no such content in "The Analects of Confucius". Moreover, the music mentioned in the Analects of Confucius refers to the "Music Classic" or music that conforms to the spirit of the "Music Classic", rather than referring to all music in general. "The Analects of Confucius" records that Confucius once said, "The evil voice of Zheng disturbs elegant music" and "If the voice of Zheng is released, the sycophants will be far away. If the voice of Zheng is obscene, the sycophants will be in danger." Zheng Sheng is also music, but Confucius hated Zheng Sheng, thought it was obscene, and proposed to exclude Zheng Sheng. This shows that music cannot guarantee that people will not learn bad things. Moreover, Confucius also pointed out from the opposite side that "If a person is not benevolent, what is the etiquette! If a person is not benevolent, what is the joy."
