Will cause whoever listens to the file to completely forget that they were hypnotised by the next file they use and every time that use 'that' file. The effects will still work to the best to their ability, perhaps allowing the person to go deeper into a trance. But causing the person to forget that they were hypnotised by a particular file.... Each time will seem like the first time and will feel like an overwhelming instinctive curiousity to listen to it. This file doesn't make someone listen to a file they wouldn't normally, just gets them to forget about a file they've already listened to.
