With so much rap in the Top 40, i'm surprised they would market towards kids.
"Rap" (or what Top 40 stations would play) is definitely palatable by many family generations. My 67 year old mother is a frequent Q102 listener.
That being said, glancing at the playlist of 1480, they're not playing any "Rap." They have rhythmic Top 40 fare, but nothing that you would hear say, on Power 99. The format of 1480 is a blend of Hot AC/Classic Hits/Oldies. All of it family friendly
