A few notes to self, should I ever have to set it up from scratch again:
- Install the Ogg Vorbis plugin from the QuickTime Components project at SourceForge.
- Create/adjust the smart playlists so that they exclude tracks that have been played in the last X days/weeks. That way you can use them in the Party Shuffle without getting repeats too quickly, which it will quite cheerfully do otherwise.
- Remove the (to me) fairly useless Radio and iTunes Store entries in the Source list.
