Why bother with CD or FLAC? If you're not listening in analog, you're losing fidelity. That's simply the nature of digital.
My thought at the time was that unless they have a string orchestra in the back seat, they're not getting the full experience.
I still maintain that a string orchestra in the back seat of my car will sound better than FLAC.
And strangely enough, even with the usually great "right to repair" laws in the EU, unless you have a very specific and expensive license that takes many years to request, it is actually highly illegal to perform certain kinds of repairs on your string orchestra.
