I had the Scourby KJV narration as mp3 files on my iPhone, but playback was cumbersome (books were in alphabetical order). The sound quality is on a par with the mp3 files. I havent explored all the features yet, but the layout is well done. This app is on my home screen. *In my teens I knew people who had the Scourby recordings on records (vinyl LP disks that played on turntables). In my twenties, i bought the New Testament and Psalms recordings on audio cassettes. A few years ago I bought the mp3 files on CDs. Each technology was amazing in its time. The Word is eternal.
