Just the idea that FM was new and they only had staticy AM before. The miracle of FM, etc. Loses relatability over time. 

kind of like like a song about wonders of cassette tapes or, maybe to be more extreme, the automobile or electric light. 

Oh I get you.   And now we have digital radio channels.  

Hard to imagine a world with just AM, just like world with just the three broadcast stations even though I grew up to some extent in that world. My parents bought me a 1980 pickup when I was 16 that had an AM only radio.
