Reboot is the mildest of the two - it will restart the player without erasing any songs. Try that one first, and let me know how it performs. Fromat and firmware will erase all songs on the player.

from what you describe the issue is from the other persons computer.

Did you try the reset button on the side under the on/off slider?

it seems like that songs was corrupted, and caused an error in the players hardware. what you need to do is erase the player completely and then find a new copy of the song that you had on there, so as not to cause this problem again

This is a normal problem dont worry, have u spilled water on it or has it fallen a few times? that might be why its doing that, if u havent done any of those things then maybe the screen is disconnected to some thing in the ds try and get it fixed

I have the 8gb Zen and I usually end up with a frozen screen when I upload music. I unplugged the Zen and then use a needle to reset the player. It located at the bottom right.

your welcome

Try inserting a pin into the tiny 'reset' hole on the bottom of the device.
