Yes, they do inspire a mood. Some are sappy. The kingdom melodies version of some are downright pleasant and do inspire a good mood. I listen to them very seldom but don't feel guilty for the good mood they provide. I dont focus on the lyrics, just the good mood.
An example of how a mood is apparent was at the funeral of a sister who wanted "Life Without End at Last" sung. Everyone tried but the tears were too oppressive. That song, so hopeful in its content, was turned into a farce and I could never listen to it with hope again. It was her funeral dirge and I thought of her with pain. Ruined it for me all the time I was in the bOrg.
