So, despite my career as a DJ, or perhaps because of it, I have developed eclectic taste in music. When I am angry, and not in the temporary, transitory sense, but rather the deep-rooted and near-permanent fashion, I prefer to listen to very calming music. I can be very explosive and temperamental when temporarily irritated, but I am utterly quiet when truly angry. It is a very calm and rational state for me.
Nothing calms me more than Byzantine chant, for whatever reason. Here are a couple of selections if you also need a similar soundtrack, watching as the country goes to pot:
The Lord bless you and keep you;
The Lord make His face shine upon you,
And be gracious to you;
The Lord lift up His countenance upon you,
And give you peace.
