I grew up listening to GT and the Halo Express on these weird plastic rectangles. Those little ditties had some staying power, and I have been grateful all my life for the way they implanted the Word in my brain. But I hesitated to pick them up for our kids because the Scripture memory songs are interspliced with narrative featuring goofy angels and Evangelical piety. I recently found that CPH has solved the problem for me with the Learn By Heart Bible Songs CD ($9.99) and Songbook (on sale for $14!). We've added it to our bedtime music repertoire. There are lots of good verses on there (including many of my GT favorites), and every song includes the reference. The singing is of the "Maranatha genetically-spliced" variety, which wears on the brain, but that's my only complaint. This would be a good resource for Sunday School or VBS, too.
