iPod Ipod Nano 2G Issue

I have a Ipod Nano 2G and I deleted ALL my music. I also restored it. I noticed when music was on my Ipod there was a blue line indicating "music". But also there is a orange line indicating "other" which is using up 1,006.2MB. What is this? I erased everything and this "other" thing won't go away. Any help?

Thanks.


Nevermind, I figured out my problem. I reset my settings, but I was trying to restore, and realized I couldn't get to the restore button because my iTunes window was not full screen.
