What about bonus or hidden tracks?

If you want a song to go out to digital distribution, you must give us all of its info like the name of the song, the composer, the publisher, etc. For obvious legal reasons, we can't sell a "secret" song. If you really want a song to remain a secret bonus track on your physical CD, you will need to upload your audio files and leave the song off of your track list for digital distribution. If we rip your music from a CD you've sent in, we will deliver that track to our digital partners.
