How do I prevent iPod from changing sleep program and resetting every night?

Not really following. iTunes Match syncs your music to your device. You can also sync using your computer. If you're listening to one track, you can put it on its own playlist too that it only plays that track.

Like muguy, I too don't really follow what you're saying. But I also don't understand how iTunes Match would "solve" anything.

What do you mean by "program"? If you mean a Playlist, then how many songs are in the Playlist and what exactly do you mean by the iPod does not hold the program in place? If you mean that when you use the Playlist the following night, it starts from the beginning of the Playlist rather than continuing from where it stopped before, then if you use the iPod to play something else, that sounds like expected behaviour.

What you can do is set a song to play from where you left off the previous time it was played. That's known as Remember playback position. It can be used on any song and that position is remembered even if you play something else in between. Is that what you mean?

Even if I set it, and don't use it, the next night it will have been replaced by something else.

How are you "setting it", what are you doing?
