Sony Erisson w580i Question

I just got my new Sony Erisson w580i today and I've been trying to figure out how to use the "Shake & Shake" funciton for the Walkman....

So anyone could teach me? I tried to shake it while the songs are playing but...ntg happens o.O

Have you enabled the option for it?

Youd be suprised how many people dont lol, I forgot to >_>;

Where do I turn it off lol? Can't find it o.o even the manual didn't mention WHERE.....

I did try to turn on both "Shuffle and Loop"
