The CD is still very much alive, in my house anyway.
At this moment in time, I don't see myself ever paying for a digital music download, call me old fashioned but I need something tangible when it comes to music. (Though I do admit to downloading and paying for games through Steam and Good Old Games.)
To me, the CD represents excellent value for money, especially if I am paying around £10 UK for a piece of music I may well end up repeatedly enjoying over the next few decades.
Your CDs will not function a few decades from now.
