I do and don't believe - not sure of what either. I'd probably be best described, as Aldous Huxley put it, "an agnostic with doubts." So, as far as music goes, I was born with this incredible gift. Trouble is, a 'gift' is, by definition, something given to one. And, since I can't fully ascribe to any deity doing the actual giving, is what I have truly a 'gift', anyway?
That said, I love music of every stripe, exclusive of nothing, and will play whatever the muse dictates at that point - as best as my natural ability will allow.
And a Merry Christmas, if applicable, or whatever you choose to celebrate, to all of you regardless of whether you believe in anything or not.
