I ran into trouble using MP3Tag for some reason. I somehow ended up messing up the tags for many songs, and I don't remember if I figured out why. Now I just re-rip when I notice something wrong with a certain set of tracks, and a lot of my earlier ripping is ripe for a re-rip since I did it with an older version of Easy CD-DA Extractor (which seems a lot more user-friendly up-front, but maybe doesn't rip as accurately) before they let you put the album art in the files. So now I try to re-rip for that, too. I just like to say "rip" a lot.
