No, I totally get why people would collect vintage cars, or vintage LPs. I don't get why people buy newly released LPs that are not vintage.
Another reason for me at least is that a lot of the vinyl I buy is directly from bands at their shows. In that case I'm getting the souvenir and I'm giving back something directly to the artists. It might just be gas money to get to the next town, but it's more than they'll ever see from Spotify.
