Worse than attempting the cinnamon or saltine challenge, try listening to “My Girl” and not grinning when Temptations lead vocalist David Ruffin sings “I’ve got sunshine/on a cloudy day.” This song is like the audio equivalent of an Instagram filter, able to instantly brighten your day (with the side-effect of making you feel stuck in the opening sequence of a 1960s period piece about coming of age). If there’s any reason to learn "My Girl", it's for your own personal health. You'll start feeling better as soon as you start playing those wonderful opening notes. In fact, you're looking even better just thinking about it. Go on, play it now.
