So, I ripped some AudioBook CD's for playback on my iPhone. The CD's got ripped into tracks like 1a, 1b, 1c... 1n, 2a, 2b... 2n, etc. The CD information and tack number information is all correctly populated, however the iPhone is still playing things back in the following order: 1a, 2a, 3a, ... 1b, 1c, ... etc. Has this happened to anyone else? Does anyone know how to fix this?
