If you've ever run across an OGG file, chances are you've probably gone - "What on earth is that?" And then you'd find out that it was an open source, slightly superior music compression format that tends to be used by the more 1337 amongst us.

Well, if you wanted to use iTunes, you were previously out of luck - or so I thought, until I found the Xiph.org quicktime plugin. This has been around for a while, but now it seems to work great.
