Amazon Music has launched the 'Themes' feature, utilizing AI technology to help users discover other podcast content related to specific episodes. By analyzing podcast transcriptions and descriptions, the feature identifies key themes and generates tags, allowing users to simply click on a tag to view a list of related podcasts. This feature is available only to users in the United States and requires the latest version of the Amazon Music mobile app. Amazon aims to enhance personalized content recommendations and improve user experience, competing with rival Spotify. As the podcast market grows, personalized recommendations are becoming a user demand.
