Since I’ve been heavily using the WordPress embed feature for tweets, I had a though that it would be nice if you could do the same thing for referencing musical releases in Discogs.com. But alas, they seem not to support oEmbed.
However Discogs does seem to have a nice client API, with a supporting Python module to boot. Seems like a Discogs oEmbed proxy server might be a nice self-contained hacking project.
