I just learned that people buy kpop albums and don’t actually listen to the CDs in them?!

When I purchased Girls' Generation albums, I copied the music into my computer and put the CD's back into the albums.
Then I'd only listen to them from my computer.
I know I could've bought the albums digitally, but at that time, I figured purchasing physical albums would be a better way to support the group because I read somewhere that only physical versions would be counted in the Hanao and/or Gaon music sales charts.
As far as photo books, I looked through them a few times the first days and thought those were nice.
Now I purchase music digitally out of convenience and to save a bit of money.
