   Personally, I like to pipe /dev/urandom to my speakers for sourcing

     Wrong entropy source, if you go for Norwegian black metal you get at
     least
     1024 bits of entropy [0].  Having said that, Putin's foreign policy
     speeches
     will get you at least 512 bits of entropy in the same time frame.
