Those, are without a doubt, the worst ****ing examples i have ever heard.
You are gonna say that all rap sucks based on Eminem and Ja Rule?... How lame can you get?... Anyway, you are taking some of those artists worst songs to make a example, why you are at it, you should go on about how The Beatles suck and then post the lyrics to Love Me Do or Wild Honey Pie and call it undeniable proof.
You are being a generaliser, or dare i say it, a racist. I mean do metal banRAB not sing about satan worshiping, bloody gore and violence?... Do punk banRAB not sing about doing smack and ****ing the authority?... Dosent 80% of all rock banRAB sing about Sex, Drugs and Rock N Roll?... Deeming all rap as offensive and with bad lyrics based on what little you have heard is a very close minded thing to do, you are ignoring the fact that there are several talented rappers, though i admit such talents are rare today, back in raps heyday, there were quite a lot of notable acts... Groups like Public Enemy and Tribe Called Quest had the balls to sing about issues that no rock band would touch with a ten foot poll, and other artists like Run DMC and KRS One who have positive messages in many of their songs, whom rarely have obscene lyrics in their songs.
So please.
