So much safer to go one album at a time using Picard. Picard makes it easy to go down the list of a disorganized directory, identify most things automatically, allow in depth review and modifications to what Picard came up with, and standardize file naming. I’ve tried to let programs like Lidarr and beets automate it, but they always ends up causing more and more complex problems to discover and solve after awhile. Music releases are complex and sources are diverse, using distinct standards of form and format. It’s not a problem that can realistically be solved for my entire music library without the guiding hand of a librarian. I could listen to my library for over six months without repeating, even 1 album out of a 100 mis-tagged or misidentifyied could take me years to discover.

I do like to automate the less critical and more machine oriented library tasks like adding genres tags, replaygain, and lyrics as you do. Just not things like the metadata tags, file naming, or album art (embedded or otherwise).
