Based on my wizard-like ability to make predictions from two data points (I did have a one-semester course on statistics, after all), I project that Britney Spears’ 15th studio album will be titled “Britney Jean Spears” (3rd = 4 – 1 = 2^2 – 1 = Britney; 8th = 9 – 1 = 3^2 – 1 = Britney Jean; 15th = 16 – 1 = 4^2 – 1 = Britney Jean Spears). For her 31st album I guess she has to get married and add a 4th name.
