This may seem a bit strange and I'll try to make it short. I listen to a 3 disc cd shelf system at night--it plays while I sleep. Now its acting up and not wanting to play the cds. Trying to fix it but I may have to find another way. So I need to know the following things 1. Can an ipod be set to play a series of tracks all night long? Basically until I turn it off? 2. These ipod speaker systems I've seen will they work with only the ipod touch? 3. Does it matter which ipod touch I use? Thinking about getting a refurb from Gamestop as I already have an iphone and ipad rmini so I just need the ipod for my sleep music. Sorry for the long post but I'm starting to realize that I might have to give up my old ways of listen to music and give up the cds. . Also sorry if some of these questions may seem stupid I did use the search option but couldn't find the exact answers. Thank you.
