To the person who made this one (I'm not sure if he's DJ Earworm), I'm giving you five thumbs up because I feel that two aren't enough. You deserve a recognition for this one amazing masterpiece. What a way to end the year 2009! :)
P.S. Listen carefully because you might hear something meaningful. Trust me. ;)
