Rick, I listen to that song you mentioned In The Blood, by Grit Laskin several times and I do find it very disturbing. It really does change my mood and I feel sad, just the same as when in the middle of a light conversation someone will tell me about a current tragic event.
I stop, think about it, feel shaken and stay that way until the conversation shifts to some other topic.
Jus the same with music, when the mood of the music shifts so does my mood.
I think is adds to the CD, offering a wider range of emotions.
Now if the entire CD was filled with songs of sadness, I would turn it off.
