Portal 2 Soundtrack [Songs to test by]

"If you've cut yourself at all in the course of these tests, you might have noticed that your blood is pure gasoline. That's normal. We've been shooting you with an invisible laser that's supposed to turn blood into gasoline, so all that means is, it's working."
Cave Johnson.

So this is soundtrack from Portal 2. Originally original. Makes you feel like you doing science.
If you start feel like you not doing science, try to play this music again, but with more volume.
If this music dont help you to feel like make science, then you gonna get fired for not making science.
Remember: Science starts with you. (and Cave Johnson)
