Interesting to see this question today after reading an article about the second sleep gene needing potassium.
Okay what happens when you listen to a Sonic Access CD is you are creating new neural networks and putting the synapses to work.
The article mentioned at the brain requires potassium to strengthen these synapses, during sleep. If you lack in sleep then the synapses don't connect and you have difficulty with learning and memory. But it seems you also need enough potassium in order to get sound sleep. If that's all true then to get more sleep eat a banana.
I don't know if that works but I see no harm in trying a banana smoothie during the day to boost a good night sleep while we're putting the brain to work with Paraliminals and Sonic Access.

As for the songs. It's seems to be agreed dorky they may be but we have more people coming back to say they love them than those who cannot stand it.
