"Singing" may be overstating the case somewhat

"Caterwauling" is too long of a word for those with the attention span of.....LOOK! SHINY!Weeeeeee!

How about a lengthy description then? "The sound of a steamroller that has been rusted still for decades screeching back to life and running over a series of cats"

"The sound of the Black Mother of a Thousand Young giving birth to a thousand young."

OK, is this OK? If I install say, Fallout on all my computers (laptop, desktop, Analytical Engine, etc.) is that OK? To have multiple copies of the same game that I own on computers of mine?

quote from GOG's Download and games FAQ
9. Can I install one game both on my laptop and desktop PC at home?
Yes. We are not limiting the number of installations or re-installations as long as you are installing your purchased game on PCs in your household. So yeah, if you've got a render-farm in the basement, you might actually break the world record for the number of legal Fallout installations in one household. However, if you think about installing your game on a friend's PC or sharing it with others then please don't do it, okay?

Why don't you just have your friend demo the game on your computer, and If he likes it, he can buy his own copy of the game. Or why don't you buy you friend a copy. Support the effort here man.
