I just imported about 40,000 songs, all lossless FLAC and about half of which were hi-rez. It took JRiver about a week to finish analyzing the music, which from what I guess means it determined the playback gain. If I want that information embedded within the tags, do I need to execute an "Update Tags (from Library)" command? I'm trying JRiver out, but if I don't like it, I'd like all the data about the files (including downloaded cover art) to stay embedded within the metadata. Thanks.
