From boingboing.net: "This is a classic example of bogus statistics. The two figures have absolutely nothing to do with each other. The 30% of people using legal downloads might be mutually exclusive or totally overlapping with the 40% that use illegal downloads. The numbers need not total to 100% (and could total to more than 100%). At best we can conclude: 1. No greater than 70% of music listeners download music (legal or illegal) – i.e., as much as 30% of music listeners simply don’t download music. 2. No fewer than 40% of music listeners download music (legal or illegal). 3. At most, 30% use both legal and illegal downloads. 4. It’s possible (based on this limited data) that no one does both illegal and legal downloading. In next month’s survey, both numbers could go up or down since the survey does not ask “do you ONLY download music from legal/ illegal sources.” Moreover, the survey provides no estimates of volumes – illegal downloaders could be downloading 10X or 10X less than their legal-downloading counterparts. Or people that download legal music could be the biggest “pirates” and this survey would be none the wiser. "
