I never really saw anything wrong with cussing especially it has been part of the environment growing up for the artist and since music is a self-expression, it is fair game imo. Like TI said when Oprah had the thing going with getting "n-word, b-word and hoes" to stop being part of the spoken language, "Sorry Oprah but n-words, b-word and hoes exist."
I think nick is well aware of your point and he is fine with cuss words cuz if you PM him that mofo has a dirty @ss potty mouth like no other. : P And from all the previous vids he has linked it wasn't the cleanest toilet bowls on the block that's fo' sho'. He does have a point in that bad words are not really a necessity but sometimes in order to get something across it might be necessary. Lets just say it's not a prerequisite for great hip hop but it is not doubt an important aspect of it.
Oh that note PREACH!!!!!!!!!
