How Long Is Your Tail?

The long and short tail are the percentage of the total amount of tracks played that fall outside and respectivly inside the cummulative tracks played for the top-n rated artists. The short tail is exactly the oposite.
If that's to much to grasp at once: To calculate the Long Tail you take a user's Top50. Calculate the sum of all the playcounts in there. Then divide it by the total amount of tracks played as listed in the user description area. Multiply it by a hundred to get a percentage. Substract it from a hundred to get the short tail. Based on a idea by itazurada.
AEP is the is the brainchild of C26000, he wrote a nice journal about AEP calculation.
