A lot of it had to do with economics. in the 80s and 90s when that garbage started getting popular, artist expectations were low when it came to standards for recording and touring for rap groups; they just wanted to get drank and fuk like niggers will do. At the time, it was way cheaper to tour a rap/r&b/hip hop artist than it was to tour a rock band since rock bands had lots of equipment, crew, and groupies. it took about 1/3 the manpower and logistics to tour a rap group around the country/world than a rock band. obviously, that has changed over the years as production values for these "artist" has increased dramatically and are now on par with a rock group. rap was also brought to the mainstream by jews, I assume for purposes of promoting degeneracy and race mixing like pretty much anything they promote. as far as the nintendo core BS, what group/s exactly are you referring to because i haven't heard much of that lately.
