Physical media is superior. Don't get me wrong, I love the convince of being able to stream any song I want, whenever, from my phone. But you don't actually own that music, not even the digital music you bought.
So having that physical backup is good. But also, it's just a fundamentally different experience, to have to put a record on a turntable, or a tape in a cassette deck, and listen to an album from back to front.
