Aha gentlemen...A long time ago, and I mean forty years and more, it was established that, Negroes listened to their radio stations more than any part of the white population, because they couldn't read and oral communication was how they got (a) news and (b) entertainment, etc. This especially applied in Chicago where most of the population came from due south and the social and economic dregs of Mississippi or Louisiana.

They were all carrying portable radios and playing neegrie music in the rear of the bus, where until recent decades, they all hung out from ol' time Southern tradition. The ghetto blaster was popular replacement for portable radios for a while and carried like a piece of luggage to parties and parks. That artifact of neeglie public culture seems to have disappeared.

The sayal phone has apparently displaced the old portable radio playing daily neegrie stations, the ghetto blaster playing CD's in addition to radio, and left the neegries able to babble freely while being mobile. They can also likely pick up ghetto music, etc, on certain cell phones or their updated technology phone-like competitors. Eventually you'll have tablet-like devices with two way visuals and neegries will be walking around holding their screens in front of their faces and merrily babbling away.

They tend to babble pretty loudly to each other on a bus as the lower classes have no awareness of the social propriety of being private when in public. It's worse on a sayal phone as they may have trouble hearing the caller so they talk louder. I can just see a bunch o' neegrie women on a bus at full roar on their sayal phones. The lowest class ones among them are the most annoying.
