This is beautifully said. There had been moments in my life when I’d be so very happy that I would indeed close my eyes, take a deep breath and appreciate the moment. When there is nothing to bug you in the back of your mind to ruin the setting, such moments are beautiful and I agree, could be described as pure joy.
I think it’s Lay it on me by Vance Joy. It has a part about him being sad, then there is love, and then an instrumental chorus to which I dance to (given a chance). I guess I find it pretty uplifting.
