I've had a Dell for many years and just got a MacBook pro today. I had saved my iTunes library from my Dell to a flash drive, and put it onto he Mac. But after synching up my iPhone with the iTunes on my new computer I'm missing about 200 songs. They are showing up on the iPod on my iPhone but not on the Mac (they are also all still on the old Dell). It seems that the ones missing are songs from songs somebody burned for me (which I of course don't have anymore).How do I get my mac library complete like my iPhone?
