I think the option "Use standardized artist names" should be turned on by default. If the option is turned off, then organizing audio files into artist folders has unexpected results. As an example, you typically wouldn't want to have both "The Prodigy" and "Prodigy" as two different folders for the same artist, just because some of the releases of this release group happen to be credited to "Prodigy" (and not to "The Prodigy").
