The primary objective was to access RSS feeds from various platforms or to create them with known structures to facilitate access to feeds, such as iTunes, SoundCloud, YouTube, and Google Podcasts. Recently, I have incorporated the ability to generate RSS feeds for Spotify shows, as they currently do not provide access to an XML file. However, this feature is limited to shows only and does not include playlists or artists.

The main focus was on accessing podcast RSS feeds, which is why the initial efforts were concentrated on these platforms. However, plans are in place to expand support to other platforms and different types of content based on user demand.

May I ask what purpose you are using the RSSPreview addon for?
