On the other hand, it's not a bad idea to use a hymnal, if you can find one you like. I really like an Episcopalian on, Lift Every Voice and Sing II: An African American Hymnal, published by Church Publishing, Inc., New York (1993). It's available at Amazon for $15.95 US - you should be able to order from Amazon, can't you, Skarpi? It's a wonderful collection of songs.
The Methodists published something similar, Songs fo Zion about a decade earlier - but I think the Episcopalian one is better.
