The storage of information as bits makes no distinction about what the information actually is. Your hard drive does not care whether the files are cat videos, financial data or files containing music. It's the encoding and decoding of the analog signal into and out of digital that accounts for sonic differences. The most common audio format is Pulse Code Modulation (PCM). Furthermore, even within PCM there are different factors and technologies that effect sound quality. One of the key factors in PCM is the clock. A stable and accurate clock is necessary to properly encode/decode music.
