If you shake this Martini Shaker MP3 player really fast, you might get some deliciously wicked symphonies to pour out. The HOST MP3 player comes in 128MB-512 MB and 1GB capacities. It is USB powered, and has a removable USB flash drive type memory. It supports MPEG, WMA, ASF and OOG. The FM trasmitter allows car stereo playback, which is great if you don't have a tape player. It's really not a martini shaker, but it looks like one, even though they call it "Bullet".
