My son sings the chorus to U & Dat and the whole call & response and hook to Tell Me When To Go....he'll be 2 the end of may....kids know what songs they like....he doesn't dance to all the songs on the radio, but he does to all the hyphy & crunk shit....its because of the upbeat tempos and how catchy the songs are....
on a side note, in a major way in 5th grade? that makes me feel old without actually being old
