Your SIL probably has a lot of the same albums I have.
I stopped listening to Rock, except for Neil Diamond, in the early 70’s and switched to Country.
When kids became teens in the 80’s I was FORCED to listen to the Rock music of that time whether I liked it or not, on in their bedrooms, bathroom and den, reverberated throught the house.
I did control the car radio, HA!
Then when the progeny cam along, I had to hear, whether I liked it of not, I too had to hear '80s stuff, until boarding school started.
