ChatGPT was configured to not output lyrics and recipes[1]. Later on they removed this from the prompt (seemingly moved anywhere else), but it's highly unlikely that such censorship will ever be removed: any citation of songs is a direct step towards a DMCA complaint, and it would be extremely difficult for OpenAI to "delete" text scattered over the model.

Other simpler models have no such censorship and can easily output both songs and their translations without specifying authors and translators.
