A holy spirit filled CHRISTIAN can easily discern which 'gospel" songs are annointed. Also, if the song itself is not 'annointed' the singer or group that performs it can surely put a spiritual spin on it and make it 'annointed', even if the writer is not a CHRISTIAN. Case in point..some of the 'best' and greatest gospel tunes on American radio has not been written by CHRISTIANS at all, or at least professed marginal fence walkers. However, in the right hands, that written tune can win many over to CHRIST. Remember "He's got the whole world in HIS hands?" or "WHY ME, LORD?" or "Put your hand in the hand of the Man", or "When you talk to the Man upstairs", or "DAY by DAY" . I was at a concert where a county music singer who was NOT a CHRISTIAN at that time, sang "Amazing Grace" complete with a black gospel choir behind him. We know the history of how that sacred song came to be. However, as this entertainer sang it, I looked around at the thousands of people who were there...and they were lifing up their roachclips, beer cans, whiskey, and pot to the sky and singing it along with him. Sometimes, it's not what we like, it's how it's presented.
