A nice workflow regarding working with album from torrents:
1: Set the music download location in a dedicated directory separate from other files.
2: Add this directory to the scanned directories in MB, and select "Add to Inbox" for new files
3: Enable auto-organization.
3: As torrents finish, select "Rescan" from the "file" menu.
4: In the now populated Inbox, apply RG (if you want) and afterwards bring up the Album Tagger. Once you select the correct album release to tag the files, press "Apply in the Album Tagger
5: Your files should be integrated in your main library directory with consistent directory/filename values from the tags. The files are subsequently removed from the inbox.
