The pre-tv and pre-internet does make a difference. With internet you can learn as much as you possibly can about a subject. Before that, you had only what you had access to - which, with music was the album covers and inserts.
I had an obsession with music, too. But my family didn't have a lot of money so we didn't buy many records. With me it was all about listening/radio/recording songs/charts. I would buy a single I liked with what little pocket money I had and then listen to it over and over again. I got a transistor radio for my birthday, and took the radio everywhere with me. I became obsessed with the charts and knew each week the top 20 songs. I got a cassette recorder one year, and would sit next to the radio, waiting for a song to come on the radio I liked to record, then listen over and over again. And every time I was upset by something, on would go the song, again and again until I felt better.
I became obessed with Germany - the country, the language, everything about it. I took the radio and found a station broadcasting from East Berlin, with rock songs. I recorded as many as possible, and stayed up to listen to a particular programme I liked until 2am, this became like a ritual to me. I started to look at cars passing by whenever I went somewhere with my family, and looked at every single car to see what kind and model it was, and to see if there were any from Germany. I longed to go to Germany, and eventually when I was 16 I managed this, on a school trip.
At one point, we got a dog (coincidently this dog was also called Honey), and I my parents bought a book on dogs/dog keeping. I learned the contents off by heart. I even took this book to school with me so I could read it on the school bus.
That passed, then it was space/astonomy. I borrowed a book from the school library and then asked my parents and grandparents to by me books. I got about 2 books, which I loved; again, I read and learned all the contents, knew the names of all the brightest stars and their magnitude. I longed for a telescope (now got one

) I once totally derailed the whole German lesson when I learned that my German teacher had a telescope and I asked him about it, so that lesson was all about telescopes

Then in the physics class, they gave all the kids a knowledge quizz. When we got feedback from that, our physics teacher expressed his dismay at the fact that no one in the class knew the answers to the astronmony questions - except for one person (guess who that was)
I was never a kid who like to talk much or share much with others. I once went 6 months barely talking to anyone. I was always very aloof and in my head. which meant that my obsessions were internalised. So I wasn't like the kid with a vacuum cleaner obesssion who always brought the conversation round to vacuum cleaners. I had difficulty keeping my attention on anything that was not my obsession and my mind would wander off and I would think about the obesssion all the time, non-stop. I became aware that it was not exactly 'normal' to be thinking about how to record songs from a radio station broadcasting from East Germany, or to be thinking non-stop about Germany or astronomy, so I learned to mask this. Clinically, looking from the outside one might not know what was going on, because it was all internalised, in my head. But that doesn't mean it isn't there.
