playlist length = p
From your list of potential plays calculate the mean length and 
standard deviation.
m = mean
s = standard deviation
Take a random sample of plays exceeding total size (p+3m)
re-calculate m and s based on your random sample
from new plays identify plays of size m-2s, m-s, m (or those closest to 
those)
remove the identified plays above from the random sample
collate playes together in play list until size is within p-2s and p
pad p the previously removed plays until size of playlist is closest to p
