The trouble with the I-Pad

I have a gazillion bibles on my I-pad. I like the ones that talk, that is the one with sound. I turn on the Book of Ezekiel for example - four hours plus and usually I go to sleep. With the cheap programs the sound crashes eventually which is fine because it keeps me from turning the sound off and waking up again. Recently I purchased a more expensive talking bible program. It did not crash last night and at 2 a.m. it started from the beginning. Thoroughly enjoyable but totally wasted night sleepwise and consequently wasted day. Perhaps I need to go back and count sheep.
