I created an audio related app that I just released to the app store. I originally started the app when I found out that my Mustang's audio player only supported mp3 (on usb key). When I first dragged the songs out of iTunes they were all in mixed codecs and some of them were not playable in my car. I created MusikAnywhere so that you can export an existing iTunes playlist to a specific codec and bitrate. This won't affect the source material. If you have non-Apple devices, this is very useful. It will also extract audio tracks from movies/video clips. You only need to select a playlist and audio codec.. Enjoy! Web site link App store link thanks!
