Thanks for the swift answer!
Ah, yes, that's important to bear in mind. This night I awoke after two hours of the sleep track and put the headphones away. I'll see if intending to put it away at the right time will work. The new thing for tonight was waking up every once in a while. I don't see it as negative effects. Holosync used to mess with my sleep at times, often making me need less sleep. 
I'll see what sleeplearning behaviors that will work the best for me.
About natural brilliance. Okay, but it seems to me that there are no changes to the paraliminals and that there is a passage that is the sleeplearning-part. It's always possible to cut the track in the right area and get the same effects, I'd guess. Hmmm... this has been a topic before. I'll do some search.
