Oh ... listened to the Perfect Meditation CD level one for the first time last night.

I must say that it was a pretty intense experience. It actually gave me a headache. I had a feeling like there was a lot of stuff going on inside of my head and felt like it was going to pop. Don't know if that is good (given the philosophy that you're "baking" while meditating) or not.

There are crackles and audio-artifacts on the disks that are irritating. The accompanying material explains that this is due to the incredibly advanced audio technology producing effects that are not produceable by lower quality headphones.

Well, it must be super dooper amazing technology, because they occur on high quality Sennheiser headphones. More likely it's just crap that the creator didn't have the technology or skill to clean up.
