Can sound waves alter your conciousness? (I-doser)

I recently ran across this website in my late-night surfing http://www.i-doser.com/

The website claims that their sound files can change your state of mind. Some claim drug-related feelings, some claim sexual bliss, etc.

I was skeptical. I mean, feeling like you’ve taken drugs through sound files? That’s stupid to anyone who thinks about it for more than half a second. I’d like to think I’m smarter than that. But it was 2AM and I was bored, so I downloaded the free app. Figuring if I was going to waste my time I may as well do it well, I loaded the “Masochist.drg” file, which guarantees sexual orgasm followed by pain. (Note each file is rather expensive. Buy/Find them by whatever means you see fit)

Figuring it would be a boring half hour and I’d probably just fall asleep, I turned off all the lights, lay down on my couch, closed my eyes, and left the program going on my headphones. The first 10 minutes I was bored. Then strangly, I began to get extremely aroused. Ten minutes later I achieved ejaculation without any physical contact what-so-ever, just by concentrating. The pain part never happened (well, my teeth kind of tingled, but not unpleasantly), but 1 out of 2 isn’t bad for crackpot internet schemes.

But my question I want a FACTUAL answer to: What the hell just happened? Can different frequency waves really spark this type of feeling? Is this similiar to hypnotism? Is this 100% the placebo effect? (Best damn placebo ever, I tell you what)

To get things started, here is some relevant reading:
Binaural beats
Brainwave synchronization

Essentially, it’s true that brain wave tend to show a tendency toward syncing with external stimuli. The idea behind these products is to try to coax the brain into alpha wave processing, which is typically associated with relaxation.

While brainwave synchronization does appear to happen, I don’t think any actual health benefit have actually ever been proved scientifically.

Shouldn’t a file labeled “masochist” consist in pain followed by orgasm?

BTW Wow, Best looking myspace page ever (that I’ve seen, anyway).
