What are some of the songs you thought you wouldn't actually know how to sing?

"Tell you I've been waiting a long time, tell you my last request, I'm gonna grab your hands, you're coming with me here." It's a direct release of the emotions that people hold in their hearts. 'Nothing' is a song you have to admit you'll quickly memorize and sing along to, just like me, who hadn't heard it before but just sang along to it all the time.
