i just want one to use for my morning jogs. im getting tired of listening to nothing, i decided a cd player that plays mp3 cds is too bulky, i need something light.. i guess 25 songs isnt very much, maybe the 256 would be better. 512 is too much, im not running around the world, and if i was, i'd just get one of the 20gig ones.. (the same size as my hard drive on this comp, technology)
