Thanks for the ideas. I've just tried creating the category view, and it's getting pretty close to what I was looking for, but there's one thing I can't figure out. Most albums are grouped separately, listing the total number of tracks in the "Number of Files" field, as expected. However, albums with multiple artists list each artist/album line separately, with 1 as the Number of Files. I tried using the Grouping setting (Customize View > Show Categories In This Order Album > Edit > Library Field: Album > Grouping: Checked > Grouping Size: 1), but this led to strange results in which one album was split across multiple list entries, while other albums were combined into one.
I assume that I'm missing something about how to group them so only the Album field is considered, and not the Artist field. What am I missing? Thanks!
