while using shuffle mode in my ipod app on the 3G, it keeps playing the same songs, and from what i can tell in pretty much the same order. it doesn't happen every time, but it's more times than not, and it's gotten to the point where i have to skip forward about 15-20 songs before i start getting new random songs. i remember itunes used to have a preference that had shuffle favor tracks based on most played (and ratings i think), but i don't see this pref anywhere anymore. not in the itunes software, or on the iphone under any of its settings. anyone else have this problem?
