The world's smallest MP3 players?

Guess we're just gonna have to take this one on faith, but Samsung says they're coming out with the world's smallest MP3 players, the 128MB YP-T5H and 256MB YP-T5V, which are just 23 x 54 x 23mm in size and weigh a mere 24 grams.
Despite their dimunitive size, both have FM tuners and built-in microphones for recording voice memos.
