I use Foobar for tagging my FLAC files. As long as your .txt file is formatted correctly, it works great. I have had some .txt files that appeared formatted correctly, downloads instead of my own shows, that were screwy when I went to use the tagger. The other thing to keep in mind if you go from tagged FLACS to MP3s on Foobar for use on your iPod etc. is to rename the Disc 2 MP3 tags because that tagging isn't so great, it will use track numbers per disc instead of going all the way through from 1-x at the end of all files. There is probably a setting to fix that upon encoding, but I haven't taken the time to check it out.
