Ok, so we've got a bunch of stupid brats singing inappropriate songs with sugestive lyrics, with only a few minor changes, and their parents providing even worse backup lines. So what's next? Are they gonna sing something by Pretty Ricky?! Or Nas?!!! They sung Britney Spears' "Toxic" and Avril Levigne's "Sk8ter Boi" and a few songs by Evenescence which are inappropriate. Buy the NOW series instead. You can hear the real artists who made the songs instead of a bunch of little brats and their sheltering parents.Mike Morrison
