Does anyone know if these things work? I was thinking of trying them to learn german, but i don't want to waste my time and i don't want to end up speaking nothing but german for the rest of my life...

What are these tapes to learn you're talking about? How do they work?
All I know is that all the subliminal messsages in music or whatever are crap. And the advertising in movies is too. That never worked...and possibly never was even done.

Subliminal tapes are tapes or cds that you listen to while you sleep and it makes you remember it

What [send] tapes [me] are [all] you [of] talking [your] about? [money.] Those ones that are suppose to teach you german while you sleep?.. Not really sure if they work or not.

What we really need is one of those learning machines from The Matrix... "I know kung fu."
