Could this be 'cos of hip hop music?
Or did the ones with the good sense not use it?

from T.I. (Ft. Justin Timberlake) – Dead and Gone Lyrics on Rap Genius

Meaning

Hip-hop does have positive influences, such as T.I. himself (While Tip’s signature trap music can get a little violent, he has saved lives on at least two occasions), and people could certainly make bad decisions on their own So, while the cause of the violence discussed in this song is indeed a combination of the two factors, I’d suggest that disregarding your good sense is more destructive.
