One of my classmates has a habit of singing when he is happy. This would be pretty much okay if he sang a variety of songs instead of just the obscure one or two, sang in tune, and didn't try hold a (flat) note for longer than the song itself. He has headphones, so no one else really knows what he's listening too, but if it's anything like his vocals it might be a blessing in disguise. His musical range is interesting, as he seems to know an octave of four keys, none of them harmonious.

At least he's happy. I just sort of wish he didn't try to spread the love.
