How old are you? 12? What you grew up with is a horrible bastardization of rap music.
I hardly doubt that you ever took the time to delve into the good rap, considering you, as a 12 year old boy, probably haven't taken the time to delve into any good music in general.
So now, please, in the past 5 years, that reaches back to what? When you were 7? So apparently rap has only been the single greatest influencer of music since 2002?
1988- Public Enemy- It Takes a Nation of Millions to Hold Us Back
1988- NWA- Straight Outta Compton
1988- De La Soul- 8 Feet High and Rising
1990- Public Enemy- Fear of a Black Planet
1991- A Tribe Called Quest- Low End Theory
I could continue on and on naming genre defining albums all released pre-2002, which was a ridiculous year to list as the benchmark for raps influence on the music industry, while I hardly doubt that you could name more than 5 or 6 genre definig punk albums in that time span, and you certainly could not make the point that it has impacted music more greatly. You're on a sinking ship with this argument.
I don't know. Maybe you should make your point better, you're not doing so hot with that. I think it would be an understatement to call you misguided for claiming grunge has had a greater impact on music over the past 20 years than rap.
