Analog is far beyond what Digital can do. Its just too complex for today's technology to be fast enough. Digital is a lot faster/more predictable, but that doesn't really make it better.
For example. The fastest way to transmit more data through radio waves? Transmit it digitally to open up more channels. Hence Digital Radio. Is the quality better? Not really, but the signals a lot cleaner, as its easier to pass over in its original form.
Anything compressed, which isn't the original form is pretty much a negative over original analog recordings.
