One of the truly fun aspects of having a large vinyl collection is to be able to use one album to trigger the response to hear something else… and something else. Having a large collection let’s you wonder through all kinds of music at will. Of course this is before streaming.
Most of us started our collections when we were young… for me 1965… when I bought my first album. I have them all… cleaned and in great shape. My collection is 2,000 all carefully cataloged, in cabinets taking a whole wall. Hoarding would be piled everywhere, never used, collecting dust. Many of my albums are carefully chosen audiophile editions.
Also, I had 2,000 CDs. Most of which I have given away. Their serve no purpose now that streaming sounds better or at least the same. I think hoarding generally means most things, not just one.
So, these things keep me in the collector category and out of the hoarded category.
