Could it be that what you describe as "new agey type words" is simply modern English, as opposed to archaic English en route to obsolescence. Also, could it be that you simply prefer the comfort of lyrics we seniors were raised with, rather than the modern and fast evolving English that our youth prefer.

As for "Lord" being replaced by "God," I presume you are talking about the Psalms and other OT scripture?  If so, there is some history behind the change that is important.

When we read "Lord," the Hebrew was often "Yahweh" (actually the Hebrew only has the consonants YHWH). The Jews and modern scholarship recognizes this as the name of God, so by the normal rules of translation of names from one language to another, we ought to read "Yahweh" rather than "Lord" in English translations. Indeed the New Jerusalem Bible, used in Catholic liturgies in Great Britain, always correctly translates Yahweh as Yahweh.
