A chart surface on the Internet recently titled: 100 American College Music Majors Analyze Japanese Musical Talent and the Relationship with the Number of Members.
How exactly this information came together is unknown, but the name suggests that 100 American music students were surveyed about several Japanese music acts past and present. Those results were then plotted against the number of members in each band.
The results certainly do suggest that there is a correlation between the number of members in a music act and the perceived crappiness of said act. So lets examine this more deeply with some samples and a translated version of the chart above.
