They tested 120 songs found on myspace. One of them later turned out to be a hit, so the researcher went back to his data to see if there was a correlation. Correlation does not imply causation. As it happens, there was a correlation. But we don't know what the songs were actually like. (Perhaps the poor songs were incredibly bad, so much so that any musician would have been able to flag them up as likely failures). We don't know much about the 27 participants. We don't know much about the experimental method. This is not well reported science.
