Of course, that's why I originally burnt them to WAV. Ages ago, I had burnt them to Apple Lossless and I didn't use error correction. Now, WAV with error correction. Took a lot longer.
If I would have known WAV files can't be tagged, I may have chosen a different lossless format that could. (AIFF?) But, all is well now. I ended up converting all the files to FLAC, keeping the WAV files, of course. Now, I have to go through and tag each album. Shouldn't take too long, using Mp3tag.
