As planned, we now have a full playlist of the all the vocalizations of our book, available at this link:
The playlist contains over 1000 songs which are organized in the same page-order as the book. In a few simple steps this playlist can be added to iTunes or to a mobile device, and then can be used as a study companion while working through the book's sonograms, playing each song or call as needed. The fee for the playlist is $5.99.
We believe this is going to be a great help in the song-learning process, are excited to offer it!
