I can remember all of the radio stations - numbers and call letters - that I listened to regularly during my youth in Los Angeles:
94.7 - KMET (rock)
95.5 - KLOS (rock)
102.7 - KISS (pop)
105.9 - KPWR (well, they called themselves "Power 106, so I assume those were the call letters) (pop/hip hop)
106.7 - KROQ (new wave/post-punk/goth/alternative)
But I can't seem to get Sammy to understand the concept of "radio." I don't mean that I've tried to explain the waves, the receivers, the amplifiers, etc. I mean, I can't get her to understand that I can't pick what song will come on next, or even skip a song she doesn't like. She has been raised with iPods, DVRs, Pandora, and streaming Netflix. Radio is very confusing to her, and she doesn't like it one bit.
And now I'm starting to understand the real meaning of the concept "nostalgia."
