Mobiblu DAH-220 MP3 player
 

Basic MP3/WMA players are commodity items these days.

They don't necessarily sound great (their bundled headphones are invariably craptacular, and they can have a hard time driving proper headphones, too), but they're so cheap that a lot of people go out to buy a USB "thumb drive" and end up coming home with one that can also play music. Or get a player free with their mobile phone plan. The things are on sale in discount stores now, for heaven's sake; they'll be in cereal boxes next week.
