In the case of "Billie Jean," Chris Cornell was credited from the outset. With "Eleanor Rigby" David identified two separate influences for the final arrangement, which goes some length towards explaining why they were not credited originally. That said, who the hell cares? Doxology will continue to dwell in utter obscurity as long as their only claim to fame is a not-so-original "cover." Now that they've received their credit they can stop crying into their beer and go back to practicing in their basement.
