This might sound a bit complicated, but I will try to explain it as I understand (which is sadly simplistic). When I import music to my computer, I use Musicmatch Jukebox because I like how it files the songs. I save all of my music in one main folder on my hard drive, which is seperate from my iTunes folder. I just recently got a new computer, and through a USB link, I transfered this entire 20-some GB folder to my new computer with no noticable problems. Today, I opened one of the albums within the folder and come to find that there are many duplicate and misnamed tracks that I had absolutely nothing to do with! How is this possible? The only difference I have noticed between the old and new computer is that Musicmatch began as the default player for all music files, but I can't imagine that making any difference. As of right now, there is no music in my Musicmatch library, and as far as I can tell no way to possibly form new tracks with wrong information. The only thing I have done with these tracks is place them in my iTunes library. I am completely confused... any help please?
