How many songs have you got on the iPod?
The number is important as too many will result in something similar to what you are explaining. Originally I could not scroll past B in songs alphabetical order.
Sub folders or albums where the first to suffer for me.
I think 700 songs or thereabouts is the limit. This is not factual but guessing as its late and Im too lazy to check the manual.
Hope this is helpful.
