I have approx 900 CD albums copied onto my homemade Win7 computer in Windows Media Player. The problem is; sometimes in a very small percentage of the albums there are 2 copies of every song in the album being displayed. Both songs will stay in the listed album until take action to remove one of them. My question is what causes the album to be copied and can either copy be deleted without losing the song completely? To delete one of the copies do I need to thru manually, select and delete each extra song?
