1. I understand that if I employ a playback API and provide a streaming service (enabling users to stream music on my website), I am not allowed to include any advertisements for monetization purposes. Is that correct?
2. Regarding a streaming application, if I offer users a feature that allows them to manage their playlists on my website, would that be in accordance with the guidelines?
