According to the eminent authorities, your problem is solved. However, what worked for me was this:
1. Show your entire audio library, and then order it alphabetically by track name, by clicking on the "name" header. This should put all track names that start with a number at the top of the list.
2. Select all the tracks with numbers at the start, and then right click, select "fill properties from file name."
3. Parse the number/name combo into [track #] and [name}. Where I put the word "and", you'll have to put whatever seperator you have there. It might me - or _ or-- or somthing. This is assuming the track numbers in the name field are correct. If they're not, send the track numbers to a useless field, like "helight", or something.
4. Check to make sure the song "96 Tears" doesn't have a track number of 96, etc etc.
5 Now you should have good track names, and presumeably good track numbers. If so, you're ready to rename files from properties, like these guys said.
