ive just got a question with the zen, the track name it displays with some of my chinese or japanese songs are just random squares and boxes whereas most of them actually show up correctly. Is there a way where I can change the display of the tracks?

For example

The track for : Elevator by Timbaland ft Flo Rida

shows up as

FloRidaPROMOexclusive-TIMBALAND-elevator.mp3

thats really annoying

can anyone help????
