I would just try a sample. It has one song with audio, which I assume is the same as the cd track. The text is reflowable, the sheet music is an image which you can zoom to fit your screen. At least with the iOS app, the audio control remains visible as you turn pages and with the usual lead in there is plenty of time to navigate to the sheet music image and zoom it. I thought it worked well on my iPad, at least when the chart is only one page, and would consider it superior to paperback + CD. More portable and convenient. But on a kindle it would be not so good.

I wish Jamie Abersold was available in digital format like this though I suppose I could scan rip and create such a thing from the ones I have.
