are doses supposed to have music in them?

i got the idoser and tried a few doses and they didn't do anything but they are all just single sounds that change a bit at some points. in the sample dose on the main page there is background music that plays with it. is mine supposed to have that? because it doesn't.

backround music is only on the cd. This sounds you are hearing when you play his dose is the binaural waves
