There is the music data aspect, but also all the rest, such as cover art, liner notes, booklets, posters, etc. Streaming and digital libraries at best give you a thumbnail of the front cover, but no back cover, no gatefold, no liner notes, no booklets, no posters.
Significant physical media holdings can also function as room treatment.
I'm going the opposite way. On my computer desk where I write my books, I used to just run Roon from my digital files. Many records are not available digitally, and I am now adding a simple vinyl rig with my computer. Looking forward to spinning records while working.
