To them, what we consider bad digital distortion is simply a part of the music that they listen to daily. Trading poorly "ripped" MP3s (regardless of legality), they have become so used to the crunchy sound quality of the format that, as some readers who have discussed the matter with their own children may attest, they may find it not only acceptable but even preferable to CDs.

FROM PROSOUNDWEB:
The crunch of digital distortion, which is not limited to MP3s, of course, but can just as easily find its way into the digital recording process and onto disc or into the live sound arena, is unpleasant. The pops, clicks, and surface noises of the vinyl beloved of audiophiles pale by comparison to the harsh distortion of digital audio, compressed or uncompressed...Is wrong always wrong? Analogue distortion can even be a major component of a sound, such as an electric guitar, and therefore desirable. If you run audio through a tube device, you are doing it to add flavor, not to reproduce something exactly or realistically. In such cases, the audio process may not be accurately recreating the original source, but it is at least adding partials that are music-related, and therefore relatively harmonious.

There's a reason why old mixing consoles, such as those designed and built by Rupert Neve, for example, are so sought after. The "warmth" controls on Mr. Neve's contemporary updates of his old designs actually introduce a modicum of distortion. That was something that was inherent in many of his original designs, albeit at low levels, yet which could impart an emotional response to the music produced through the equipment that made it attractive to the listener.
