Bigpond music store & songbird integration

I like to buy my music. Unfortunately, the 7Digital music store is only for the UK. Australia (where I am from) has an online music store by bigpond that is very competitive with the iTunes store (http://bigpondmusic.com/). I am curious to whether there is a way to create an addon to access this website from songbird and download music straight into songbird (among other things) like the 7Digital store does.
