4. Justin Timberlake
Before Selena Gomez & Justin Bieber, pop music had Britney Spears & Justin Timberlake. Their break up holds a special place in my heart, as it was the first time I learned that love was dead. All I had left to make sense of the tragedy was JT’s “Cry Me A River.” And with not-so-subtle lyrics like You don’t have to say what you did, I already know, I found out from him, I made sense of it pretty quickly.
