The playlists linked from the program guide now go all the way back to the dawn of time (or 2004, in any case). (They had those playlists online in the old site, but the only way to get at them was to manually try different numbers in the aforementioned CGI arguments; here, they're indexed in nicely paginated indices going as far back as necessary.) Here is the first International Pop Underground playlist they posted online; it's interesting to note that Carew played My Favorite's Homeless Club Kids and various Stephin Merritt-related projects that week.
Also, RRR's website will have a subscribers-only section, which will apparently include expanded audio archives. Not sure what exactly this will entail, or indeed what Australian copyright law will allow.
