Thanks for your reply Rick. I'll try to better explain my problem.
I am a classical music lover. I have been using MC for several years but use it only for my audio files, almost exclusively for managing and editing metadata, etc. I use another program (dBpoweramp) for ripping (all FLAC) and play my music on my stereo system through a Squeezebox Touch device. My collection of classical discs now stands at 975 CDs, so I have a fair amount of data and many files.
My most useful Library Views include the fields "Artist", "Genre" and "Album." For me, I use the Album field to describe the work. On rare occasion, I would like to re-define a work (Album) such that I now have, say, two albums comprised of the individual music files that had been previously included in a single album. I can easily accomplish this through one of the two procedures described in my first post. The problem is that when I try to view them (or play them) from my Library View, the changes I have made do now show up. It's as if I never split the single album from one album to two.
I hope I better explained the situation.
Thanks again for offering help,
Dave
