Do/Have you used a CD/DVD/Bluray in a while?

What about burning a disk?

I'm surveying modern day awareness/usage of optical media, mostly to confirm some demographic theories, so if you know what a CD/DVD is, please help me (and maybe others) out by answering some ~10 questions here:

And then please boost for better visibility! Thank you!
