I'm involved in a project that will be launching as a marketplace for various types of digital downloads, e.g. music, movie clips, apps, etc. While this site is being developed out it was decided to launch it in beta on a purely affiliate-revenue basis so it can start earning revenue and also so we can start building links and traffic ahead of the official launch. We have populated our games section using an XML feed from a partner company, but we're having difficulty finding similar feeds for our other sections (music, movies, sports, apps, TV shows, etc.) When searching for feeds on affiliate sites all we seem to find are online retailers dealing in physical goods. But the criteria of this particular project is that they must not be physical goods, they must be downloadable content only. Can anyone recommend a good source of digital download-only XML affiliate feeds?
