Music artists and film makers have remastered and edited some of their albums and movies for digital/streaming services, and if you don’t have the original physical media you won’t be able to enjoy the work of art as it was originally released. Everyone knows Star Wars with Han shot first, or ET with guns being switched to flashlights, but there’s a lot of examples. From the simpsons being edited on Disney+ to Canadian rapper maestro fresh wes’ hit Let your backbone slide just missing from streaming services, you can not rely on the content you’re looking for to be there.
I don’t know if I’m still allowed in this club. I just spent December and January ripping all of my movies onto a Plex server so that I can access them easier throughout my home, but I don’t plan to get rid of any physical media. I have about 400 DVD and bluray, 700 cd’s, and 200 vinyl.
