There are some that have beautifully written melodies. Listening to old kingdom songs makes me nostalgic since I remember falling asleep to them as a kid. I grew up with the brown book before the change to the new one. I'm not very fond of the new songs that are always played from the new songbook, the melodies aren't that great and a lot of the older songs that appear in the new book are hardly played.
Some I like:
God's Loyal Love
Life Without End at Last
Forward you Witnesses
Zealous for Fine Works
