Black Eyed Peas Album: “Let's Get It Started [Canada]”

i thought that it was really good. i am thirteen, not under. now that radio disney (radio station) plays black eyed peas on the radio, they ply "lets get it started" and also "let's get retarded" they shouldnt play "let's get retarded" on a childs radio station. my sister, who is 9 years old, listens to "let's get retarded" and even sings the lyrics. half of the words she doesn't know what they mean.
