I listened for a second and I heard him say "We be those Hebrews". Why can't they at least do it in real English?
It would depend on the rhyme which is being rapped, I don't particularly recall in which song that line is used but at this point I have heard some incredible rhymes from some of these guys. I have been listening to Nossan Zand from Boston, Mass lately and he is pretty talented.
I surely realize that everyone has different tastes in music, so I don't expect you to like it like I do. My musical background, if you have not heard before, is mainly 80s Rock (Rush, Styx, Yes, Van Halen) and Heavy Metal (Metallica, Iron Maiden, Black Sabbath) and I was quite a Deadhead in the 80s (saw the band 40 times). For a long time I refused to listen to any rap because all there was at the time was the 'gansta rap' which I was (like it seems some here) very vocally against. There are still discussions on the Internet from those days (90s) in the 'rec.music.gdead' usenet archives where I was called a 'racist' for being against gangsta rap, but what is interesting is that at that time I was also for 'gun control' which I am firmly against today.
Anyway, don't watch the videos I post if you find them irritating. I find the lyrics mostly inspiring and listen to these songs on my car stereo (with sub-woofer) and they sound great (and not rumbling like those creeps who drive by with distorted speakers).
