Why won't my Amazon MP3's sync onto iTunes?

I downloaded two albums today from Amazon.co.uk via the usual Amazon mp3 downloader. But, when I open iTunes and sync my iPhone, the albums do not automatically appear as normal. Yet, the files for the downloaded albums are in the iTunes folder in 'My Music'.

Why not just buy from iTunes?
