I really do not know, I guess I get so lost. I love silence or just natural sounds,like now all I hear are the birds, breeze and my one deep tone windchime. And of course the snore of the bulldog,and my hound scracthing reminding me she needs a bath dangit. lol, the background noise of the tv makes me crazy. I will have to pay attention I guess ,I do agree it puts you into a meditative state when it is mindless sticthing.
Sometimes in the winter when the house is closed up I listen to a Native American flute CD and I do like audiobooks as well.
