You're kidding right? Maybe not as much as today, but there was plenty of variety, it's not like Tex Ritter and Count Basie were doing the same type of music. The era saw an explosion of new styles including Rock, Smooth Jazz and Bebop. And don't forget there was a lot more on the radio than music, since there was no television. They had talk stations at the time with as much political bias as today (Charles Coughlin for instance), news programs, sports, dramas, comedies and variety shows. This was the era of "war of the worlds" and "The Shadow". Rockstar kinda missed the boat on the immersion train with that one. I guess though as long as the game runs, they didn't wanna rack up their licensing costs.
I was to lazy to look into later on I second guessed myself after I posted that but eh whatever.
