The music streaming service Deezer is developing an AI tool to help determine whether new songs added to its library should be flagged as explicit. The new tool is still in development, but company executives hope it will help them sort through the up to 40,000 new tracks it receives every day from record companies, most of which are unlabeled. Once finalized, the tool won't automatically label tracks, but instead flag tracks for review, which will be conducted by one of the company's executives. 'When it comes to figuring out what explicit lyrics are, there is no general consensus,' Deezer's Manuel Moussallam wrote in a blog post outlining the new project. 'It's obviously a cultural issue, with lots of considerations about the intended audience and the listening context.' 'As is the case with movies, the primary objective of tagging a piece as "explicit" is to provide guidance to determine how suitable it is for an intended audience.'
