Am I correct that you are un able to add a song from Itunes library. I was trying to add audio in the pre countdown. I accessed my iTunes and it will not allow me to insert the music. Is this a format type like mp3 and not mp4?
The only supported audio format is mp3. I encourage you to suggest additional desired formats (or any other desired feature) at http://proclaim.uservoice.com where other users can upvote your suggestion for inclusion in an upcoming release.
Jeff, if while in iTunes you will right click on your music you should see an option to convert to MP3. The downside is you will now have two copies of the song in your iTunes library.
