For some reason on my iTunes library, there are two of the exact same artist categories when I use my browse feature and my iPod. One of the two will only have one song, and the rest will be on the other. This occures on about 5 of my artists. There are ABSOLUTELY no differences between the two in spelling, capitalization, punctuation, etc. What's wrong?! I'm obsessed with my iTunes library and spend hours maintaining it so every one of my 17,000 songs has every piece of info (artistm genre, etc) which is very hard to keep up with when you download music from LimeWire. Please help me! Thanks!
