I always edit the genre so that the tracks work correctly with my various different smart playlists. In rare instances I'll also need to tweak the artist name to fit with the existing tracks in my library. Sometimes the album or track names have extra info that I don't care about and will delete. And TV show metadata is usually a mess and needs quite a bit of editing.
