1. when playing music/audio books on my 8 gig iphone, i like to know how far along i am in the song. My old ipod aloud me to see song progress, but i cant seem to find that on the iphone...is there a feature that allows me to see the little progress bar? 2. is there a feature on the imac that allows me to turn the monitor off but keep the computer portion on so i can play music while i sleep with out having to deal with the bright screen? 3. With the little remote control provided with the imac, there is a little menu button that lets me scroll though and play my music in a different screen than itunes. in that same music area, i can choose any music, movies or what ever. When i sleep i want to play a cd on loop, but i cant find the loop feature only a shuffle feature. does that music player have a looo funtion or only itunes does? thanks!
