Does Match do the same thing as the iTunes Plus thing I am getting offered on my account? As in for £17 I can upgrade all my purchased songs to non DRM high quality music with iTunes Plus, or for £22 I could upgrade all of those songs, as well as all the low quality rips I have DRM free?
Apple Updates its support documents to include the new countries that can get itunes match:
