Use Apple Lossless format.
Apparently some people have used wav format on their iPods, or so they have told me.
I don't know at what exact point the Holosync soundtrack starts and ends but I can assure you that it's only required during the Sleep learning track. It there is any during the first and last track it will be centered around the alpha frequency and you'll be able to get there by listing to Paul. I am sure they focued mainly on the sleep learning track for the Holosync soundtrack,
