As I have mentioned before, the greatest mix site off all time was Dirtcastle.com (which no longer exists). Well, I'm here to tell you all that the greatest thing to hit the web since free porn recently launched in the form of 500mixes.com. The site was created by Dirtcastle founder, EJ Nord. The site is specifically built for the mixtape aficionado by allowing visitors to stream and download mixes by genre. I can tell you all firsthand that the site is perfect for selecting a musical landscape while you read all the salacious details surrounding the Manti Teo/Notre Dame hoax story.
