The reason "The Greats" survive the test of time is usually because their great texts are sung to great melodies that forever lodge themselves in our memory, making them accessible to us at any moment, in any place. This is one of the great powers of music - it's ability to cement those things associated with it (both good and bad) into our memory.In his book, Christian Leaders of the 18th Century, J.C. Ryle offers his thoughts on the power of good hymns.
Good hymns are an immense blessing to the Church of Christ. I believe the last day alone will show the world the real amount of good they have done. They suit all, both rich and poor. There is an elevating, stirring, soothing, spiritualizing, effect about a thoroughly good hymn, which nothing else can produce. It sticks in men’s memories when texts are forgotten. It trains men for heaven, where praise is one of the principal occupations. Preaching and praying shall one day cease for ever; but praise shall never die. The makers of good ballads are said to sway national opinion. The writers of good hymns, in like manner, are those who leave the deepest marks on the face of the Church. (382)
