I’m guessing that your definition of spirituality goes beyond Christianity.
It include Christianity or any other cultural expression...
Some didgeridoo is sacred music for me as well as Hildegard of Bingen ...
And no i did not grow in Russia. I love Russian musicians especially their pianist school and vocal tradition ...
For me i love musicians more than music. musicians are music...
It is why i dont bother with styles or genres but more about specific musician ...
Any music rooted in spirit or rooted in the Earth soul is sacred music and i love it more than anything else ...
As an exemple by Michael Nyman and some fabulous Indians musicians :
