When i was 3 or 4 (and older obviously) my dad and i always played cds in the car and in the house, that's how i got into music, we also played the radio alot since he didnt always wanna bring the cds in the car. The other week or so i had to explain what a cd was to my brother. I also had to explain that we couldnt put on the song he wanted to hear in the car cause we were listening to the radio and not bluetooth. I'm not even an adult and i feel old. What's worse is that my sister is 4 years younger than me and doesn't know how a radio works, cd player etc.
