Can someone help me with a problem editing metadata using PerfectTUNES? I have no problem with editing tags on ripped CDs and no problem with most downloaded HD albums. I am very frustrated however, that some HD downloads have grayed-out metadata fields and I cannot add or edit. Nothing appears in the fields (ie no album, artist, genre, composer, etc) when browsing the files and folders on my PC. In addition, the tracks, titles do not appear when browsing the folders/files with my PC. My digital music player(Lumin U1) does display metadata for these files. Some of it is incorrect and this makes the sort and find functions problematic - thus my desire to edit.
