That's nothing. You should check out the record collectors.
It must be more daunting to have a huge number of records than a huge number of books. No matter how fast you read, you can in principle read faster, so even a rather large collection is within the potential reach of a human life, even if you read slowly for now.
Records take a well-defined amount time to listen to properly; once they add up to more than the longest human life span, you know you'll insult at least some of your collection by never once listening to them.
Books and records, guilty and guilty.
I have broken down and given several hundred of each away. You'd never know I'd bothered. All my bookshelves are filled two-deep.
I removed my "I've read but still want" books to the Rubbermaid Archives in the basement.
I bought a new Crosley so I can still play my 78's and 45's.
