Recently acquiring an album in Ogg Vorbis format (.ogg files), I was disappointed to realize that they do not play in iTunes. After a bit of searching on the Internet and a bunch of false leads, I'm hear to share with you the best way to do this. There is no need to convert Ogg to MP3 or Ogg to AAC. This tool does not seem to run slowly and works even on the latest Intel Macs, problems other solutions seem to have. (Also note – Windows users, sorry, this only applies for Mac OS X users!)

All you need is the component for QuickTime (upon which iTunes bases its playing capabilities) from Xiph.org. It's a free download from http://www.xiph.org/quicktime/download.html.

A note on installation - Put the .component file in your ~/Library/Components directory, which you may need to create. So if your short user name is "jones" then go to your home directory, "jones", and then Library, and open or create the "Components" folder. Also, if that does not seem to work, close QuickTime and iTunes. Re-open iTunes and you will see you can import and play .ogg files just like MP3!

Enjoy.
