This kind of subcounscious programing works even if you don't know the language the subcounscious is far more inteligent than the counscious mind, the subcounscious rules everithing in the body and as i know some parts of the conscious mind, it is the feminine aspect of the mind and rules the hearth beats, temperature, some memory, creating blood cells, organs and other parts of the anatomy of the body. Also in some cases destiny can be changed trough the subcounscious mind. It also has access to the so called "mass mind" of the people that can influence all people in our civilization, by having that conection it knows what the lyrics say.
Also avoid programimg yourself trough others like hypnotherapy. They can even wipe memory so that you have an amnesia abount what happened during therapy. They can also make you do things that you wouldn't want to do consciously. Avoid also online "subliminal messages" you can do it yourself trough trance meditation from TempleofZeus.org or by recording the affirmations you made or have and listening to them in the morning after you wake up and at night before going to sleep, they also work when you are sleepy, or at night when you sleep. Also don't start programing yourself when the moon is in void of course.
Music is also an effective way to program the subcounscious mind.
