Last week iTunes sent out iTunes 7.7 with Software Update, and now Shuffles don't work due to problems with the "podcast" playlist that's been added.
Several semi-solutions are discussed in two threads, one named "Shuffle not playing - charges and its recognized?!?!?" and another (with a better title) at http://discussions.apple.com/thread.jspa?threadID=1599361&tstart=0
Basically, moving songs into the iPod's "podcast" folder (NOT the "podcast" folder in the Library) is a fix, or maybe deleting iPod's "podcast" folder but this may cause problems. It's confusing (especially because the symptoms are the same as those leading to pages saying "flashing orange and green lights of death" with no solution in 2006) and I wish Apple would send out a warning immediately, and fix iTunes ASAP.
