Okay, this is a bit of a problem for me. I can solve it one way, but its my guess that there is a faster way. Here is what happened: On my iMac, somehow someone created duplicate tracks that were linked to the exact same file. ie. It shows 2 of the same songs that are actually the same file, not different ones. So, I didn't know this was possible to begin with and so when I went through to clean up duplicates I saw A LOT of them. Some of them were right but others I could tell shouldn't be there. So I went through and started deleting some of them. one thousand or so I deleted of the duplicates. Then when I decided to take a break from doing that, I went to listen to some music in the normal view mode and thats when I noticed some of them were missing. All the ones that I had deleted. So, I understand that those songs are now completely off my iMac, however I have most of them on my windows computer. What is the best way of getting the music of my upstairs onto my iMac? To answer my own question, here is my initial thought. Go through my PC and select the songs I need and put them on the iMac. The problem is that this will take an hour or more to do since I will be going through thousands of songs one by one to see which link is broken. How would you all go about solving this problem? Oh yeah, don't worry, I am going to do a backup of all the music as soon as everything is neatly organized and back in order on my iMac. This will take me some time and dvd's since I have almost 30gb of just music.
