(TOOL) Would you meditate to or sleep with a Tool song without knowing it's intended meaning?

I have wih only certain songs - the ones I know what they are. However, they also have songs like Prison Sex, as well as frequent insertion of random sounds and more "higher"-type sounds, which could possibly, if they have enough knowledge, be designed to activate specific areas of brain. Clearly Tool are not "okay people" regardless of their stance against the Churches, and obviously I do not want to absorb the effects of anyone who is capable of entering the mind of a rapist or who sees them as human beings. However, that does not mean that other unknown songs are also disgusting. So perhaps other people know whether they purposely engineer sounds like that, or whether Prison Sex is the only song that should not be entered into someone's subconscious. Some have good sounds but unknown meaning, and if it were another band, such as Godsmack or Backstreet Boys, who is unlikely to be engineering sounds, I would use them.
