So now I have a RVW-enabled RSS2.0 reviews feed, for any person or machine who happens to be interested. I tried to do an RDF one as well, but couldn't get the data to fit. Here's the standard Movable Type RSS1.0 template - if you can find a way to put the same data into that I'll put one of those up as well. And yes, it does use an Amazon identifier, but only because the MusicBrainz site is still impossibly hard to use.
