This category is only for sites which feature music in WAV format. If the site contains music in any other format, you can find the appropriate category in Arts/Music/Sound_Files.
If the site contains audio other than music or is not limited to music (for example famous lines from a movie or television program or humorous WAV files), it does not belong in this category. Other categories to consider include:
Arts/Movies/Multimedia/Audio and Computers/Multimedia/Audio/Sound_Archives/General_Collections.
