Hey guys. I had bought a bunch of cd's back when I owned a Windows PC and ripped them all onto my computer. When I got a Mac I burned all those folders of music to a DVD and imported them into iTunes. It went pretty good except some songs didn't get grouped into music CD's like the rest. Out of 1000 or so songs 50 or so did not get grouped. See picture below: What do you think I should do? Is there a quick way to fix this besides editing all the songs individually?
