Help with Itunes please

I just bought Audiosurf, which is a game that takes your music tracks and then creates nifty little racetracks out of them for you to play on. It's a great time waster.

However, Audiosurf cannot read my Itunes songs that I purchased through their online store because of the DRM. I've been trying to remove it for the past hour, and I'm getting a little fed up.

Is there any way to remove DRM on the newest version of Itunes for free, or should I just suck it up and buy Notebook?
