bliss's auto tagging just provides bare-minimum tags such as track name, number, album name and artist name. There's plenty more to do, such as find cover art, fix file and folder paths and fill in year and genre information.
This concludes the auto tagging tutorial. Hopefully you've learnt a little about music tags, how bliss works and what you'd expect to see when you use bliss. Your next step is to download bliss, install it and begin filling in those tags!
