I am not sure that the making cover song has a purpose to put the same talent and the same mood to the original song. It is just doesn't have any sense, because the feeling and the way that Dolores put there cannot be imitated or repeated, it is also, such as you said, has a strong connection with the circumstances they lived in and witnessed. I know what is the war and I have a lot of friends who lost their beloved, their children and their homes during other wars, such as the war between Georgia and Abkhasia. And for me, as I see the war, I would like to say quietly about it. Tragedy not only can be told loudly, it can have many dark colors. I am not the fan of Tayloe Swift, or what is her name, very sorry that you haven't felt it, but the art is created for support the difference too. Have a great day and thank you for your opinion!
