Kid-friendly hip-hop recommendations
Good bets in general:
De La Soul
Biz Markie
Eric B and Rakim
DJ Jazzy Jeff and the Fresh Prince
Everything before 1985 (Sugarhill Gang, Spoonie G, Treacherous 3, Grandmaster Flash, Fab Five Freddy)
Current pop radio hits aimed at pre-teens are usually fine for little kids too, ie Willow Smith, Black Eyed Peas etc, though these may get on your nerves
Instrumentals -- I especially recommend J Dilla and 9th Wonder
Here are all the hip-hop tracks in my collection that I can certify to be kid-friendly, profanity-free, and most importantly, good music! (I made the executive decision that kids can handle some minimal exposure to "hell" and "damn.")
