If they are CUE/BIN files the script will be able to handle them all without a problem. My advice is to use the ‘-flac’ argument when running the script, so you get lossless copies. But you should double-check the resulting CUE sheet, after processing each album. See if any of the pregaps are longer than a few seconds, cause in rare cases there’s hidden bonus tracks in the pregaps. If that’s the case, you can extract the pregaps separately with the ‘-pregaps’ argument. Good luck!
