Seriously. I've had this on in the background for the past 20 minutes, and I have no intention of switching it off. It's called Chell in the Rain, and it does exactly what it says on the tin. It pairs gorgeous art of Chell, from Portal, with the Feels Like A Trial song, and the sound of rain pattering in the background. Now this is a very literal description, and it kinda removes the magic from the whole thing, but I guarantee if you open this tab, you'll have a very hard time closing it.
There's something about this song, it just loops perfectly! It never ends, and you don't want it to end either.
