You could break this down to the various methods of listening but in particular, CD?
Of my age group, virtually every answer is, ‘…but it was a gift.’ They were new to us and as a young adult (teen but I moved out at age 15) trying to make ends meet, I didn’t own a CD player for several years. I held onto that CD gift, though! They cost about 40USD for your ‘LP’ (not box set) CD in my area. That’s WHEN THEY FIRST CAME OUT. I don’t know how to cypher the inflation on that to see what it would be in today’s USD but holy crap!
EDIT: I found this calculator for adjustment. It says $99.16. That’s what I mean when I say ‘most my age received as gifts.’
Mine was Duran Duran. I felt like a rock star to own a CD, even that I couldn’t listen to yet!
I got a hand-me-down electric record player that folded up and looked a bit like a hat box. Even the youngsters probably have seen what I mean in old movies. I had a book with 45 record about Henny Penny (a gift) and one that had ‘The Good Ship Lollipop’ * on one side, can’t recall the other (also a gift). My first purchased 45 was Queen. I did a lot of 45s because that’s all the money I could get together. I scavenged others and finally started scavenging LPs. I cannot recall my first but I know that I only had like FIVE forever: ELO, Jimi Hendrix, CSNY, The Beatles and Gordon Lightfoot. I also had access to 8 Tracks but only when people were gone, as I didn’t have a player. I got my first CD player in the 1990s. I still have a record player — a much nicer one that was part of a component system but gave away my vinyl back in the 80s when I had to move out. I’ve done a blog post about the ones nobody would take — still have those gnarly things in the barn, of all places.
* Oh, and Shirley Temple is dead. We weren’t close but I did have that record.
