Oh, I totally agree. I was just using the list to illustrate what a diverse mix top 40 really was. You could hear The Beatles, Tommy Roe, and The Temptations all in a row. Since there weren't a lot of alternatives (8 tracks??? :yes

you often had to settle for something you normally wouldn't listen to.
Hell, as teens we were always pushing those car radio buttons looking for something good. Up in Milwaukee, I had the locals WOKY and WRIT, plus WCFL and WLS out of Chicago until the "underground" stations like WZMF and WTOS popped up and we had to go to Olsen Electronics for those cheesy FM converters.
Back in the early 1980s when i lived in Chicago, I used to listen to a lot of WXRT as they were pretty eclectic. When I'm there now, I'm astounded that there are still some of the same DJs left damn near 30 years later
