Yes, I agree there is evil out there, but I believe the more we surround ourselves with love and positive vibrations the more we keep the evil away. I know people who love this kind of music will say it's ok but it does attract lower energies. This could be the case with the lyrics as well. So is with swear words.. I will give you an excercise to perform. Go in front of your mirror look at yourself and say f*** you, see how you feel. Then come back in 10 min look at yourselve in the mirror again and say I love you. See how you feel now.. Blessings
