Yes, that is the main complaint against the MP3 - or the bottom line . Regardless how it is "specified" in scientific terms. I do not find listening to music on public transport in high quality reasonable or justified. Simply, too much noise etc to warrant anything above CD redbook - most likely even well below that quality. At quiet of the home, it is another story. Our country is too small for the Spotify to consider it - so, no experience on that front either.
