There you go. And my point, ultimately, is that some people care about quality and others seem not to, so it would be important to note whether that criterion is important to the current user or not, or, possibly, to what extent.

We've been going back and forth on that. The whole question of ease-of-use comes into play. The hope is that the weights could auto-correct themselves based on how successful they are. Like, if a particular song scores high based on quality rating, and the user gives it a 1, they probably don't agree with the quality assessment. Then on another, if their rating is more in line with what the system predicted, the weight of that factor would increase. This type of stuff makes my head spin, especially when you consider that most attributes aren't in just one dimension like the "quality rating" is. But we're doing what we can, and as long as we can B.S. our way through it, I'll have my Masters degree, and thus, have my weeknights and weekends back. Hoo hah.
