> covers require a mechanical license, which is compulsory Which is compulsory for the performer too. A derivative work like cover is sort of acceptable when it's performed by a person live for some audience (grey area but twitch sort of allows it. with a bunch of rules). As soon as you want to publish it you MUST have a license. And chatbot is a derivative work totally not performed live by a person for some audience I saw great tracks that got taken down from all legal channels because they featured a sample from another song. Sometimes they remained up but mostly they were taken down. It is fully original publisher's discretion...
