Back in the days of Windows Media Player, Microsoft had a genre called Children's which contained releases that were aimed at kids. I have some albums that are Christian children albums (such as artist/b725aa44-e273-4af5-b5ec-b4a5b80a36f2) and other children albums (such as release-group/0a563f36-0932-36be-9a8d-13c5c67a07fc) that could be fit under one of the Christian genres or pop, folk, etc., but are still different from the other releases in those genres. I believe it would be a better fit to be able to classify these under their own genre. Also if I choose to listen to all the pop songs in my collection, I don't want a kid's pop album to come on right after Bonnie Tyler.
