World Acoording To GOB, The (GOB) Easter Egg - Hidden Spanish-Song

At the last song (called "The Perfect Remedy"), wait a couple seconds. Soon you'll hear something like a shower in the background and some guys talking in Spanish*. A couple seconds later a Classical guitar will start playing. It will be joined by another and it will start sounding like a slow spanish song, but it picks up speed. Some more Spanish sounding stuff and in the end you'll also hear someone say "Show me the money". After that, it fades out with more guitar and more talking.

*It may not be spanish, just what it sounded like.
