Taylor Swift doesn’t do much collaboration with other artists, but when she does, she does them well. Breathe is a lesser-known collaboration with Colbie Caillat from her second album. It chronicles the first few moments of a breakup. You know the moment, the realization that this person isn’t in your life anymore. You don’t know how you’ll breathe without them, but you have to. It’s an absolutely heartbreaking song, but it’s so beautiful, and it will help you pick yourself back up after a breakup.
