ZCR renames the CDG and MP3 file inside a ZIP file to match the name of the ZIP file, allowing your MP3+G collection to be better organized. This is also much quicker than unzipping and renaming both files.
MP3+G to ZIP pairs the MP3 and CDG files created when you rip a CD+G and creates a single ZIP file from them, saving a considerable amount of space while making your karaoke collection more organizable.
