If you ask me, the Audiofly Remix is the best version of this song. There's also a club mix, but in my opinion it sounds like someone is taking a hammer to your brain when you listen to it...sooo, I didn't include it in this post.
One last note, Mad as Hell can be heard on Fabric Live 21 (not to be confused with Fabric 21). Check it out.
