Sounds... redundant.
The only reason I can see for wanting to constantly play the tapes over and over again is a major self-doubt as to one's own abilities, combined with a major doubt as to the effectiveness of the tapes.
How about, listen to one of the tapes once and then spend the time you would have spent listening to them over and over and over again to actually learn or [/B]remember[/B] what it is you want to?
And give yourself, and Learning Strategies Corporation, a little credit. If I can loose 35 pounds listening to Ideal Weight once a week (Side A on Sundays, Side B on Tuesdays), then certainly you can manifest similar results with Personal Genius and Memory Superhcarger without resorting to desperation efforts.
I hope this helps.
