Dune (Dune) Easter Egg - Hidden Track

Choose the last Track 13 "...in the end". The cover say it plays only 8:05. But when you fast forward about 10 minutes a hidden track will plays. I don't know how it calls.

Sounds a bit like some parts from Track 12 "make sense". And sounds a bit like a sound test.

And these 2 tracks sounds that one channel is broken.
