You've got a tough, important job and you're pretty good at it. Of course, "pretty good" may not be great, but you don't need to be great. You just need to make sure that every note is correct (or at least close to it) and that whatever you might be singing is appropriate for the setting , and so far you're batting a perfect record on that score. You have yet to cause a major singing catastrophe, and for that you thank your luck, your angels, and your mediocre skills. This one's for you, World's Okayest Singer ! We salute you with a t-shirt and hoodie!
