Joe,
Definitions would be helpful and maybe some examples too. My 80 year old friend Fannie quotes often from the hymns her parents would sing. They were primitive Baptists (Calvinistic) and those hymns were rich in doctrine and were Christ centered. Probably many were the same as the Presbyterian hymns. Years ago, when I attended an arminian country Baptist church after becoming a Christian, I remember singing the song "If I could only hear my mother pray again." This is what I would call sentimental, without any Biblical content. They weren't all that bad though.
