that's totally off man. Lost & Found is hip-hop at its best. i think ur saying that all stuff thats is ol skool is hip-hop and all new stuff is rap. i would have to disagree. there are still artists that make hip-hop today.
now as far as what Damian said, technically hip-hop is a culture, a way of life. and rapping/emceeing is 1/4th of the hip hop culture. but today, alot of people call old skool and clean rap "hip-hop" and newer stuff "rap". but the real meaning behind the words hip-hop and rap was already stated. hip-hop = culture, rap=a way to rhyme words over a beat
