I agree there is no obvious superstar like we usually get one or two of (well, arguably Robin Thick), but otherwise I'm hard pressed to say anyone on this list doesn't seem to be a fine representation of their era/genre. I'm not a Christian rock fan, for example, but these guys seem to be a big deal if you are. I'd rather Universal keep a hodgepodge format like this than, say, the aging Gen X acts of Food & Wine or the ready-to-keel-over Boomer acts of Flower & Garden. Let the kids have some fun, too.
