Hiya G!
I don't listen to either of them and get spectacular results. I can't go into depth about why it works but this link does:

I just relax and doze off for a few minutes and voilá the tape is finished and throughout the day I will feel the changes. It seems that I get better results this way rather than stressing my brain about "listening in the middle" that is the common advice. My theory is that as long as my brain is listening to it, it gets in. My conscious awareness is not needed. Just stuff it in. =)
This works for me, I don't know about how the others do it.
Cya!
