There are some who say that music is profoundly powerful. Sound is profoundly powerful. words are also more powerful when accompanied by sound vibration. So it can be very healing. Or cause imbalance, as the case may be. I think that if we gravitate to music that matches where we are, but has some clarity in it, can be a good thing. I think it can even be healing. I really can understand why you are gravitating to that song D&D. It might match where you are now. Whomever wrote the song, I think sees some real truths about how many are living in the world in not a very good way. Sounds like the person who wrote the song doesnt have thick blinders on. that can be painful. It hurts to see the imbalances in the world caused by hatred etc.

can we pretend that airplanes in the night sky are like shooting stars? i can really use a wish right now.
i'm not afraid to take a stand
Everybody come take my hand
We'll walk this road together, through the storm
Whatever weather, cold or warm
Just let you know that, you're not alone
As I said, sometimes listening to music that matches were we are, and also holds some kind of comfort as above, can really be healing !!!! Music is very powerful, I think.
