yeah. i actually had my mp3 player (nomad jukebox zen xtra 30gb) somehow refuse to recharge one day, and i had to scramble to back it up before the battery went dead, which almost worked. luckily the friendly creative nomad folks sent me a new one for free, but i still every now and then have a hankering to listen to some obscure song only to realize it was on my old player and didn't make it to the new one.
i, on the other hand, really hate shuffle. i mean, if you pull up a genre and shuffle it, that's fine. but something about weird war -> miles davis -> le tigre -> heavy d -> erasure -> brahms just doesn't cut it, and ends up pissing me off.
