I have about 300 CDs in the garage in boxes, a little under 100 in the house. Mostly stuff that’s not on Tidal like the (old) GU, Balance and Renaissance CDs, plus some other stuff. I have about 800 vinyl records left, enough to fit under my DJ desk, so storing them is not an issue. That space is there no matter what. Wife and I have together about a thousand books. And about 600 Blu rays.
We like physical media. Marie Kondo would have a seizure in our house.
