1. Keep doing what your doing, and don't be lazy

2. Put all your tracks in a folder, drag the folder, it will put them in order.

3. You probably have iTunes sorting them via alphabetical order.

4. iTunes is recognizing your mp3/wav/or whatever files from your desktop.

5. When you move your music from your desktop to a different location iTunes still thinks their on the desktop and will try and find them in the desktop folder and when it can't, it will give you the error message. Don't put them on your desktop in the first place, put them in your music folder then drag. Taking the few extra seconds to stay organized is important.

EDIT: also would have probably been better to ask this in Chit Chat, woulda gotten more responses.
