Flash drive that plays music?

I'm looking for a small, keychain-sized flash drive that can play music too. Think iPod shuffle, but smaller (thats a little too big to fit on a keychain ). 1GB minimum. Any suggestions?

I think this is something you're looking for. http://www.nomadworld.com/products/MuVo/
I have an older one and I really like it.

the ipod shuffle is smaller than that.

the only one that is barely smaller is the mobiblu dah-1500i available at walmart. its a goofy shape and doesn't have a built-in usb plug, though. i think the shuffle is as small as you can get with a built in plug.

here are some pictures comparing the shuffle to various flash drives
