I also knew lots of women in the 60s and 70s. NONE of them had any interest in a system, or wasting time sitting still, doing "nothing", just listening to music.
And here in 2023, just like the OPs post in 2015, just like the 60s and 70s, I still don't know a single woman who has the slightest interest in "doing nothing but just listening to music!!!".
