What do we know about mp3 players?

Ladies and gentlemen, the time has come for me to purchase a new mp3 player, because the battery on my iPod is crapping out on me in the worst way (it only plays for an hour or so before needing to rest, bless its little ... parts). I don't want or need anything fancy (and I definitely don't want anything expensive), just something that's small enough to strap to my arm, has an FM tuner and can hold enough music for, say, an eight-hour flight, give or take a few hours. To my knowledge, Apple doesn't have a product that matches these specifications. Do you all have any recommendations?
