Ok, I'm gonna ask you to run this program. It's called the
media collection reset tool. What it does is it makes the software re-read your entire collection as if it was the first time. This does nothing to your settings or device. You can use this to get a better understanding of what the software actually finds as far as music and stuff goes. After running it, if you still see those problem songs in the collection then there's another issue. If you don't see them, then we can go from there.
