Ok i admit. I'm not a brain music expert. I really am not sure whether this CD emits sounds that will make me more creative or open up my alpha brain waves like the cover says. I've tried and I don't really feel any different. And yet I'm admitedly intrigued by the warnings on the label that say "do not use while operating heavy machinery" and such. However, the cd provides only a single song - if you call it that - that lasts for an hour - and its really just a low thumpy staticy rain noise that remains fairly constant and does not ebb and flow. Nothing really mind blowing if you ask me. Also, the packaging looks more backyard than mass production leading me to believe the $23 price is also a bit high. Ok experts, flame away! Tell me I'm simply not smart enough to get it. Perhaps that is the case... either way I guess i expected something different.
