I don't like assigning "quantitative" values to qualititative assessments.
I don't like 'Best x of the y', where x and y are literally anything you care to imagine.
I don't like comparing disparate forms of art to each other (usually via aforementioned quantitative values)
So anyway, this is my favorite album of 2015 by a healthy margin. No, it doesn't matter that I'm writing this in June.
